I don't know if anyone else has noticed this, but when I used the L4a "Set Custom Chrome to No" command I got a noticeable increase in performance.
I originally tried this for my Nettop installation (Win 7 x64 4GB) to clear the dual monitor bug, and found that after changing that setting, the scrolling speed is actually usable on this system (dual core Atom processor doesn't have the horses to run L4 well).
Just to confirm, I tried this setting on my laptop (Vista x32 2GB) and found the scrolling to be snappier as well.
Question to our friendly L4 developers: Are there other eye-candy settings you might feel like allowing us lower-end hardware users to change?
