I too have an annoying 0.2sec delay whenever i did alt-tab switching.... and i found a solution!
It's actually configurable... for some reason compiz defaults an "alt-tab" delay of 0.2sec. You need to change that from 0.2sec to 0sec.
I'm on 11.04 btw.
Go to Control Center -> CompizConfig Settings Manager
Click "Static Application Switcher"
Click "Behavior" tab
Change "Popup Window Delay" from 0.20000 to 0.
Voila! Now pressing alt-tab brings up the switcher INSTANTLY.
