OK, I'll retry my tests several times more.
But I've never seen OSD utilize 10 cores, so... I won't believe it until I see it myself on my machine. :-))
It's better to see evidence with your own eyes of course!
I tried a fresh OSD on a block ramdisk ("brd"), for example. It was eating 658% CPU and pushing only 4138 write iops...
If you have the time to investigate, you might try gdbpmp or Adam's
wallclock profiler to see where the OSD is spending it's time. That
might help diagnose where the OSD is bottlenecked. I would certainly be
interested in the results. We have quite fast systems in the lab but
very limited diversity of hardware.
