Found a couple of tips that really work,
Remove Delay on Boot Menu
sudo gedit /boot/grub/menu.lst
Find timeout and change it to 1
Save the file and close your boot menu file
Use All Your Cores on Boot-Up
If you've got a dual or quad core processor,
sudo gedit /etc/init.d/rc
Find the line with CONCURRENCY and change it to:
CONCURRENCY=shell
Save and close the init file
Profile Boot-Up
Bootup normally and hit e to drop into the terminal, then add profile to the end of your kernel's startup line. Don't save this file, just let it boot up once b to profile your machine.
When you bootup it'll be slow while it's profiling, all the rest will be much faster
Disabling Unused Program On Startup
Goto System / Preferences / Sessions and hunt for Evolution Alarm Notifier and un-check it, if you're never gonna use Evolutions Alarm feature; I don't.
Install Preload
Make Ubuntu more intelligently monitor the programs you usually use and keep them in memory on startup by installing the preload package
sudo apt-get install preload
