--- 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 a=
lso
does it synchronously, IIRC, which reduces the performance (a little on SSD=
s, a
lot on NVMe).
