Hi,
I am running a chromium based webkit port on mipsel linux. I have
recently updated the codebase to 10875:
http://src.chromium.org/viewvc/chrome/releases/19.0.1068.0/DEPS?view=markup
I was previously running a code base from Oct2011. For some reason
with the new codebase, javascript slowed down by a factor of 100 (ex:
v8 benchmark suite). I am not very familiar with v8, so I thought
maybe someone might give me some pointers/ideas to attack this. One
(hopefully relevant) datapoint:
When running the v8 suite, if I stop the browser, the first resolved
function in the stack is usually one of these three:
v8::internal::LoadIC_Miss, v8::internal::CallIC_Miss,
v8::internal::Runtime::PerformGC
Thanks,
Levent
