Unfortunately, I no longer have access to the dual-X5550 system, and I did not try other values for this parameter when I was benchmarking that system. On systems that I do currently have access to, the slowdown from GOMP_SPINCOUNT=10000 was typically no more than 10% (and most of the time there was either no effect or substantial speedup). I can try 100000 on those, although it'd be difficult to tell the difference from 10000 because of the changing load. I'll plan on doing this next time I run this sort of benchmarks. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43706
