Yeah, that bit is backported to Firefly and can definitely help, however
the suggested initial value is too small for most people who have scrub
issues, starting with 0.5 seconds and see how it goes seems to work better.
Thanks xinze, Christian.
Yah, I'm on 0.87 in production - I can wait for the next release :)
In the meantime, from the prior msgs I've set this:
[osd]
osd_scrub_chunk_min = 1
osd_scrub_chunk_max = 5
osd_scrub_sleep = 0.5
[osd]
osd_scrub_chunk_min = 1
osd_scrub_chunk_max = 5
osd_scrub_sleep = 0.5
Do the values look ok? is the [osd] section the right spot?
Thanks - Lindsay
