zzz: any scope for shunting some of the eventpumper load onto NTCP Finisher threads? they seem underutilized right now.
dr|z3d
NTCP reader threads are being exercised more, writer threads, not so much, and then finisher threads least of all.
zzz
dr|z3d, we just did a big shunting with the ntcp write changes
zzz
there's no need to balance workload across threads
zzz
and jogger would tell you the opposite
dr|z3d
ok, just noticing the finisher threads are less noticeably less utilized than both the reader and writer threads.
dr|z3d
*noticeably less utilized
dr|z3d
if I constrain the pumper thread it's happy to use around 50% of one core under loads of ~1MB/s
zzz
probably a candidate for removal of the finisher threads
zzz
jogger hates all of it
dr|z3d
yeah, jogger's not a huge fan of the "let's throw threads at it approach", understandably, given android.
dr|z3d
android/arm
dr|z3d
more arm than android, but yeah.
zzz
not sure if arm is worse at threads than x86, or if it's just worse at everything
dr|z3d
probably the latter for the most part, given the specs of the usual candidates vs x86 (raspberry pis)
dr|z3d
still, if the finisher threads aren't serving much purpose, sounds like a reasonable idea to eliminate them.
zzz
just takes time to analyze and test, and of course be extra careful not to introduce deadlocks
