The following will only improve the ext4 file system so you Raiser people need not read on.
So I installed e4rat
E4rat is a utility that’s designed to cut your Linux boot time drastically. Essentially you show it what you do when you start your computer normally, and it analyzes the files you access and use. Then, it’ll move them to the beginning of your hard disk so that it takes less time to find them during boot.
If you are using SSD there will be no gain in using e4rat.
E4rat is available as a .deb package for *buntu users. Others may have to compile it from source.
Setting it up:
I edited /boot/grub/menu.lst and added
Code: Select all
init=/sbin/e4rat-collect
This will only be used once so you must remove it again after one boot.
So time to reboot and e4rat will now collect what happens and move the data to the front so it starts faster - kind of defragmenting the boot process.
After two minutes you must edit /boot/grub/menu.lst again and replace
Code: Select all
init=/sbin/e4rat-collect
Code: Select all
init=/sbin/e4rat-preload
And check that /var/lib/e4rat/startup.log is created and contains (collected) data.
Now it is time to reallocate and that is the tricky part:
Type:
Code: Select all
sudo init 1
log in as root and type:
Code: Select all
e4rat-realloc /var/lib/e4rat/startup.log
You will not be able to copy and paste this command so you better write it down before you do the init 1
This may take some time.
After that you can reboot and enjoy your Ferrari.
