--- Comment #24 from Johannes Singler <singler at kit dot edu> 2010-11-12 08:15:56 UTC --- If only one out of 35 tests becomes slower, I would rather blame it to this one (probably badly parallelized) application, not the OpenMP runtime system. So I would suggest a threshold of 100000 for now. IMHO, something should really happen to this problem before the 4.6 release.
