I've started adding a couple fixes to gtkperf (including code from the pts test to let it run from the cli).
So far the only big test I've changed is I've made "add text" much faster and also forced it to actually update the screen. Previously, on some machines it takes a full hour during which the screen never changes.
Current changes are here https://gitorious.org/gtkperf-fixes/...commits/master
I would eventually hope to get it included in PTS.
Thanks for your suggestions,
