Reporter: bos | Owner: simonmar
Type: bug | Status: new
Priority: high | Milestone: 6.12.2
Component: Runtime System | Version: 6.12.1
Keywords: | Difficulty:
Os: Linux | Testcase:
Architecture: x86_64 (amd64) | Failure: Runtime crash

Comment(by simonmar):
After applying the patch from #3553, on a dual-core 1.2GHz Intel Core,
Ubuntu Karmic:
* HEAD, unthreaded: ~6300 req/sec
* HEAD, -threaded -N1: ~6600 req/sec
* HEAD, -threaded -N2: ~6600 req/sec
* HEAD, -threaded -N2 -qg: ~6600 req/sec
the numbers wobble around quite a bit, but as far as I can tell the
problem is now gone. I'll wait for confirmation from Bryan (maybe when we
put out a 6.12.2 RC?) before closing the bug.
