Hi,
OK, thanks for testing. Maybe we can get to the bottom of that at some
point ...
Best,
Carl

Just tried during the encoding with activity monitor open, and
disabling logging had an immediate and undeniable effect.
Logging is slowing the single decoder thread?
I'm sure there is many factors involved, and some of them may be
machine specific.
Thanks!

Logging is indeed the cause.
0.6 fps with all logging activated
1.3 fps with all logging except debugging
4.4 fps with no login
Strange. Just checked 1.76.42 on my 'standard' slow test machine (DualCoreHT
notebook) with all logging disabled vs. all logging enabled - no difference. Will need to
check with a faster machine with more cores. It's clear that more threads create more
logging, and the faster the machine, the more the logging slows is down, but I
wouldn't have thought that the impact is so huge. Maybe also should compare Mac vs.
Windows.
