The changes will most benefit having multiple apps open at once. I have noticed a more stuttering under canola as well when it's paging. I'm trying to figure out if it's paging in or out.

In reality these tweaks should slow down your average benchmark in a nominal way, but more of a synthetic benchmark... say two people doing the same thing should show more responsiveness.

Placebo... possibly, that's why I'm hoping to get feedback. The browser tweaks appear to help most people, but the other tweaks might be more questionable.

Ajax.. yeah, I think it's an unfortunate side effect of the async, non-persistent nature of the connections. I'm looking at mozilla's help for a possible solution to that problem. It's not going to be easy, but any help will be better than it is now.

wmgui... dunno, sounds like it might be something that can be solved with some sysctl changes ( assuming the CPU is up to the task ).

I'm testing on a n810 -> wifi -> 10m/1m cable connection. Some on the sites I'm using are Google reader, timesunion, livejournal, google search, facebook ( iphone ), and netflix.
