This is no compalin, since make buildworld works with one thread. But I'd like to report a funny thing I witnessed. On two boxes equipted with Core2Dou CPUS (E8500, 2 cores/threads, Q6600, 4 cores/threads) a parallel make buildworld works fine with the most recent sources of FreeBSD 10.0-CURRENT/amd64 (both boxes have 8 GB RAM, both boxes use a very close/similar setup and configuration). I moved in my lab towards a brand new Sandy-Bridge-E box with 32GB RAM and the CPU is a Core i7-3930X with six cores/12 threads. On this box, even "make buildworld" with -j2 fails to build. It builds fine with a vanilla "make buildworld". Also funny is, that even with only one thread, the 3 GHz Core2Duo methusalem systems "outperform" in compile time the 3,2 GHZ driven Intel youngster. Maybe there is an issue in FreeBSD 10 with the TURBO BOOST? I'm a bit time constraint now, but I'm willing to do some tests with advices from the experts. Lets give you some informations I think it could be valuable. Please request more, if this isn't sufficient. I realize/I'm aware that both hardware and OS are brandnew! But hopefully this is something important and could be "fixed" - if my observation is a real observation ...
