https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=242427 --- Comment #7 from Peter Eriksson <pen@lysator.liu.se> --- > keg_free_slab: keg->uk_freef(mem) {page_free} took 2190 µs > keg_drain: while()-keg_free_slab-loop took 163 s (163765748 µs) [240297 loops, 4 slow, avg=681 µs, min=246 µs, max=7922 µs] Just a FYI: The "max" value should probably be subtracted with ~6000µs - calling printf() with a line of text seems to take about that time - so if I run the same test without printing anything in keg_free_slab() the max is around 2000µs instead. -- You are receiving this mail because: You are the assignee for the bug.help
