Go to http://www.satine.org/research/webkit/snowleopard/snowstack.html

It is very very slow both with compositing enabled and disabled, both in the webkit nightly and in chrome. This regressed in chromium r63327, which was a webkit roll from r70157 to r70206.

http://trac.webkit.org/changeset/70170 looks most related in that range.
