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.
Speed up Windows Vista booting process
In Windows Vista while booting it uses only a single core of your PC irrespective of multiple cores available. To utilize your processor during boot up follow the steps given below.
How Enable booting up with multiple cores:
1) Go to start->run->msconfig and press enter.
2) Select the boot tab.
3) Click on Advanced Options.
4) Check the appropriate number of ports according to your system configuration.
5) Click OK.
