When I use run-webkit-tests to run the entire test suite, on a debug build of TOT WebKit, on Mavericks, I’m having the following problems:
Yep. The time from 31k to 33k is a long as from 0 to 31k :(
- Towards the end of the run, instead of the 8 parallel copies of DumpRenderTree, only 1 copy of DumpRenderTree seems to run. This is running mostly the svg/custom tests.
I think the problem is we can only run DumpRenderTree in parallel on different folders. Toward the end, everything left is one or two slow folders.
The problem is partially that the sharding is folder-at-a-time, partially that the svg folder is big and slow, and partially that "svg" comes near the end of the alphabet (i.e., we don't start the big slow directory until close to the end of run, so there ends up being one big long pole).
At some point we added code to run-webkit-tests to have a list of "slow" directories that got started towards the beginning. I don't remember if we did that before or after the Blink fork, but it would be easy to port it over from Blink if it was after.
I'm pretty sure this was after the Blink fork. I did a quick look through the history, and I found this:
Is that the correct change? If it will make tests run faster in WebKit land as well, I'm more than happy to port it myself. :-)
