--- Comment #90 from Don Lewis <truck...@freebsd.org> --- When stealing a thread from the other SMT thread on the same core, another tuning knob comes into play, kern.sched.steal_thresh. A thread will only be stolen if the that value, which defaults to 2. My previous experiment used the default, but for my latest experiment, I set it to 1, to match the hardwired value that is used for stealing from other levels of the hierarchy. The results were definitely poor. In addition to the usual ghc SIGBUS, lang/guile2 failed to build due to a SIGSEGV, textproc/p5-String-ShellQuote failed in the fetch phase when make got a SIGBUS, and editors/libreoffice failed to build because of a clang SIGABRT. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
