  * [[https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217214|PR 217214]], [[https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218270|PR 218270]] are closed, but %%NetAPP%% is experiencing this in stable/11 based builds. Happens during high loss scenarios. rscheff@ is still looking at it. Workaround seems to be disabling SACK.

  * rrs@ is working on hystart++ for the RACK stack. The code is under review at [[https://reviews.freebsd.org/D32373|D32373]].

  * glebius@ gave an introduction to SMR locking. The code is under review at [[https://reviews.freebsd.org/D32585|D32585]]. It will be further tested at Netflix and finally be committed to %%FreeBSD%% 14. No MFC planned.

  * There was some discussion on tools being used for performance testing. The list included [[https://github.com/google/neper|neper]], [[https://trex-tgn.cisco.com|TRex]], and [[https://github.com/uperf/uperf|uperf]].
