REGRESSION(r116210 - r131528): Hindi line-breaking on TOT is 5% slower than Safari 6.0.1
Obviously the real regression range is much smaller. r116210 is when safari-536-branch (Safari 6) was made from trunk.
The microbenchmark in question is attached to bug 100024. I wrote the microbenchmark to make sure that the 8-bit TextRun optimization (bug 99393) wouldn't be a slowdown for complex text for the harfbuzz ports.
It's also possible that the microbenchmark a. doesn't test what I want it to. or b. isn't interesting and that this isn't a regression we care about.
