No, because it satisfies one thing you asked for: measuring tlb shootdown performance: ./tlb -c tlb: 16 pages 0.75218 nanoseconds If you look at the code, this is probably exactly what you need: the difference between the case with tlb misses and without. _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "freebsd-performance-unsubscr...@freebsd.org"
