https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228359 --- Comment #10 from Warner Losh <imp@FreeBSD.org> --- (In reply to freebsd from comment #9) what's the mb/s for the TRIMs? There's a sweet spot for TRIM requests that varies based on each drive. just trims each of the blocks in sequence, which is a lot of trim requests. It also does it synchronously, IIRC, which reduces the performance (a little on SSDs, a lot on NVMe). -- You are receiving this mail because: You are the assignee for the bug.
