just started with 8.4 devel. Still focussing on LWlocks. With the
same load (#users & benchmarktool) I now see LockID 11
(CLogControlLock) to be in the top waiting list.
This one was never noticable in 8.3.
Did anything change with respect to this?
Thanks
Paul

Uh, no, 8.4 devel has hardly started and I can't think of any changes
we've applied that would be likely to change the load on
CLogControlLock. What is your test case?
