--- Comment #10 from Krutika Dhananjay <kdhananj at redhat.com> ---
That's interesting.

I actually ran pure randrd job again on Sanjay's setup (through vms) with the
best configuration known yet and with mempool and mem-accounting disabled in
code last week. And I saw that the FUSE thread is consistently at 95% CPU
utilization. I'm running perf-record on this build right now to see where the
thread is spending all its time.

As for the perf record output above, I think using the "-call-graph=dwarf"
option should also get us the backtrace, though this would require
glusterfs-debuginfo package to be installed.
