Hi
On 3.4.1, I had a crash server side because of system limit (heap size). I
restarted, and now the fs is extremely slow.
Here are profile info. Any hint of where is the issue?
With lookups taking bulk of the time, was there any self heal in progress?
Did the situation recover after a while or has it been the same?
