https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248652 --- Comment #34 from Vincenzo Maffione <vmaffione@FreeBSD.org> --- (In reply to Sylvain Galliano from comment #33) Ok, thanks. At this point it's clear that there are two indipendent issues = that slow down netmap-iflib on ix/ixl. The first is the lack of a per-tx-queue netmap timer (or taskqueue). The second is the lack of descriptor writeback moderation in ixl. We can start by merging the timer patch, and then work on the separate ixl issue. --=20 You are receiving this mail because: You are on the CC list for the bug.=
