Linux rarely needs to be rebooted. But when it does, it’s often slow to boot. Fortunately, there are ways to speed things up. Some of these methods are not terribly difficult. (although some, unfortunately, are). Let’s take a look.
#1: Disable unnecessary services
Depending upon the use of the machine, plenty of services won’t be needed. Using Linux just for a desktop? Then you won’t need sendmail, http, and many other services. If your server is only a web server, you can shut off many services as well. To do this, you can go to the Administration menu and take a look at the Services entry. Just deselect all of the services you don’t want to start.
#2: Disable unnecessary kernel modules
If your desktop is wired to the Ethernet, you don’t need to have a wireless kernel module loaded. This task is a bit more difficult and will require a kernel recompilation, which is not the easiest task to undertake. To do this, you will need the kernel sources. Then, follow the standard steps for compiling a kernel. The difference is that you’re going to go through your system and disable all of the modules you don’t need.
The best way to find out what kernel modules currently install and run on your system is to install Bootchart. Not only will this give you a good list of modules, it will illustrate for you what is happening during your system boot. You can also issue the command chkconfig –list | grep 3:on to find out what services are running. Once you know what loading modules you don’t need, you can remove them during a kernel recompilation. While you’re at it, compile the kernel to exactly match your architecture.
#3: Use a lightweight window manager instead of GNOME or KDE
I plug smaller footprint window managers for a reason — they drastically reduce graphical boot time. Instead of having to wait that extra 30 to 60 seconds for GNOME or KDE to boot up, why not wait two to 10 seconds for Enlightenment or XFCE to boot up? Not only will they save you boot time, they will save your memory and the headache of dealing with bloatware.
#4: Use a text-based login instead of a graphical login
Most of my Linux machines boot to run level 3 instead of run level 5. This will halt at the text-based login, where I only have to log in and issue startx to start my desktop of choice. The graphical logins do two things: increase load times and create headaches trying to recover from an X windows fubar.
#5: Use a lighter-weight distribution
Instead of loading the heavyweight Fedora, why not try a Gentoo, Arch, or Puppy Linux? The boot times for these smaller distributions are far faster than the more bloated Fedora (and even Ubuntu). Of the larger distributions, OpenSuSE claims to boot the fastest, but I have not personally tested this. Between the latest Fedora and Ubuntu, Ubuntu blows Fedora’s boot times away (and that is out of the box).
#6: Use an OpenBIOS
If you’re savvy enough to upgrade your PC’s firmware, you might consider migrating to an open source BIOS. One caveat to using open firmware is that it allows Linux to actually initialize the hardware as it boots (instead of relying on the BIOS). On top of that, many open BIOSes can be configured to meet your machine’s specific needs. If you don’t go the open BIOS route, you can at least configure your BIOS to not search for a floppy drive that’s not there or to boot directly to the first hard drive (instead of the CD drive first).
#7: Avoid DHCP
If you are working on a home network (or a small business network) where address lease isn’t a problem, go with static IP addresses. This will keep your machine from having to call out to a dhcp server to get an IP address. If you take this approach, make sure you configure your /etc/resolve.conf to reflect your DNS server addresses as well.
#8: If you can spare it, get rid of hotplug
Hotplug is the system that allows you to plug in new devices and use them immediately. If you know your server won’t need this system, delete it. This will cut down on boot time. On many systems, hotplugging consumes much of the boot time. Removing hotplug will vary depending upon the distribution you use. NOTE: udev has, for the most part, replaced hotplug. But if you’re running an older distribution, this does apply.
#9: If you are REALLY daring, you could give initng a try
The initng system serves as a replacement for the sysvinit system and promises to drastically decrease boot times in UNIX-like operating systems. If you would like to see the initng system in action, you can give the Pingwinek livecd a try.
#10: Use a hack with Debian
If you’re using Debian, there is a simple hack you can use to switch your startup scripts to run in parallel. If you look at the /etc/init.d/rc script, you will see: CONCURRENCY=none around line 24. Change this line to CONCURRENCY=shell and you should see a reduction in boot times.
That’s about it. Of course there are always more and better hacks out there. But the above should mostly cover everything. The good news is that you’re most likely already running Linux, so the burden of boot times is generally eased by the infrequency of reboots.
Okay so everybody saw lately Google Chrome which is preety damn fast internet browser. Interesting why did they manage to make their own browser while they pay 70% of Firefox revenue to be on their bar right? Of coursde they just want to gather more info about you 
Stuff shown here is simple to be made and will really make the browser work better and faster .
For starters lets stop Firefox from eating so much RAM! This may preven loose of your data so you wont need files recovery. Increase Computer Speed And Stability By Removing Corrupted Registry Files With Registry Toolkit.
Anyways lets get back to business.
Tak off the amount of RAM Firefox uses for its cache:
1. Type in browser window about:config
2. Find – browser.sessionhistory.max_total_viewer
3. Set the value to 0
Reduce RAM usage to around 10MB when Firefox is minimized [i bet this kills your memory sometimes with many tabs open!]:
1. Open Firefox and go to the Address Bar. Type about:config and then press Enter.
2. Right Click in the page and select New -> Boolean.
3. In the box that pops up enter config.trim_on_minimize. Enter.
4. Select True
5. Restart Mozilla Firefox.
Increase the Speed at Which Firefox loads pages
1. Type about:config into the address bar and hit Enter.
(Normally the browser will make 1 request to a web page at a time which is wack. When you enable pipelining it will make several at once, which really speeds up page loading.)
2. Alter the entries as follows:
Set network.http.pipelining to true
Set network.http.proxy.pipelining to true
Set network.http.pipelining.maxrequests to some number like 12.
This means it will make 12 requests at once.
3. Lastly, right-click anywhere and select New-> Integer. Name it nglayout.initialpaint.delay and set its value to 0
And that is how we speed up newest version of Mozilla Firefox 3.0.8 and all other versions.
regsvr32 /u shmedia.dll
I have had a number of requests for how to documents on dual booting Windows and Vista. Since the process for Vista and XP are different I am going to give them separate articles. I will start with dual booting Vista and Linux This tutorial will focus on the Windows portion of the process and will only mention the issues surrounding the Linux installation that are necessary to make note of.
Of course I have to make mention to back up your data! You never know when something could happen to cause you to lose precious files.
Well, let’s begin…
Fundamentals
Before we go into the how to on this it is best to discuss what dual booting is and how it is possible. I will mention that the most important issue with setting up a dual booting machine is that Windows MUST be installed first. Because the Windows boot manager is a very single-minded boot manager, it will not recognize any other operating system. To that end, the Linux bootloader must be used.
Now dual booting is exactly as you would expect: A single machine with multiple, working operating systems installed. Upon boot of the machine the Linux boot loader (typically Grub) allows you to select which operating system to boot. This set up is very nice for those wanting to make the transition to Linux or want to use Linux but have Windows to play games on.
Getting Vista Ready
Vista did some things right. One such thing is hard drive partitioning. With Vista you are able to re size a parition, on the fly, without damaging data. Microsoft hid this tool a bit, so you have to know where it is. To open up the Computer Management tool click on the start menu and then right click the Computer entry.
Click on the Manage entry from this new menu to open up the Computer Management tool.
Now it’s time to click on the Disk Management entry. Once you click on that you will see your machine’s hard drive in all its partition’d glory.
There are two parititions on this drive. The larger partition (141.61 GB) is the partition to re size Right click on that parition to open up a new menu. From this new menu select the “Shrink” entry.
Partition managing menu
Once you select Shrink a new window will appear asking you how much to shrink the drive.
Shrink window
The amount of space to shrink will be the partition your Linux installation is on, so make sure you create enough space.
Once you click the Shrink button your machine will go to work re sizing your partition. Once the partition has been re sized there will be unallocated space on your drive.
In the image above I only re sized the parition a small amount. You will need to create a much larger portion of unallocated space to install Linux
Once the partition has been re sized, it’s time to load Linux.
Installing Linux
Since there are numerous distributions I will only touch on the key aspects you need to watch for. Most likely you will be installing from a Live CD so boot the Live CD up. Once the Live CD has finished booting click on the Install icon to begin the installation process.
The first section you need to pay close attention to is the partitioning of the hard drive. What you need to do is make sure the installation uses the free space on the drive. You most likely will have to select the Manual partitioning, but don’t let that scare you. Once you select Manual you will have options to select. There should be the equivalent of using only the free space on your hard drive. Do NOT select anything remotely equivalent to Use Entire Disk. If you make this selection your Windows installation will be erased.
Once the installation partitions the drive it will install all the files it needs. Upon completion of the system installation it will be time to install the boot loader. Just accept the defaults because the Linux boot loader must be the first thing to load on the machine.
Once the boot loader is installed it’s time to reboot. You will notice when you boot (again the exact wording and look of this will depend upon the distribution chosen) there will be a few boot entries. The default entry will be the Linux operating system. If you do nothing within 10 seconds Linux will boot. You can use your arrow keys to select the Windows choice and hit enter to boot into Windows.
Final Thoughts
Congratulations, you now have a dual booting Vista/Ubuntu machine. It’s really that simple.
SoftwareTip'sPalace offer you full Guide for Microsoft Windows Vista Installation. First we will explain you few important things which you should know about Windows Vista before you start with Installation. Most important thing you should know is Windows Vista Requirements, so first read which Windows Vista Requirements are than you can start with Vista Installation.
-----------------------------------------------------------------------------------------------------------
Windows Vista is the new operating system developed by Microsoft. After more than five years of development and several delays this new version arrives from shadow. What it more emphasizes when initiating this new version of Windows is its graphical surroundings denominated AERO. Adored by and criticized by others when saying that it is a copy of MacOS X, which is certain, is that it is a great step if we compared it with the previous versions of Windows. According to Microsoft, Windows Vista is the most important version that they have sent since left Windows 95.
Before anything, you have to know that Windows Vista requires quite powerful equipment so that it can work fluidly. Although Microsoft has given two data:
Those of Redmon have created a tool to know if your equipment can or cannot run Windows Vista as well as which is the version that better adapts you computer. This tool can be downloaded from this link.
Note: Before you start with Windows Vista installation please read Requirements for Window Vista.
Windows updates may fail in Windows 7 or in Vista with the Error Code 0×80070422 with the following error in the c:\windows\logs\CBS\CBS.log file.
80070422 SelfUpdate Failure Software Synchronization Windows Update Client failed to detect with error 0×80070422
This can happen for two reasons,
To resolve this Windows Vista or Windows 7 update issue, set the Startup type of respective services to “Automatic” & “Manual” respectively.
Follow the steps to resolve Windows Update error 80070422:
Important:You must be logged on as an administrator to perform these steps.
Note:First you want to reveal the hidden admin account in Windows Vista and login to the hidden admin account.For this do the following:
net user administrator /active:yes
You should see a message that the command completed successfully, logoff and login to the true admin account.
