[Gluster-users] heavy metadata issues?

Hi folks

  Seeing some metadata slowdowns in some cases on GlusterFS 3.0.3. 
These metadata slowdowns manifest in terms of long ls, long stat, long 
rm times for directories with a few thousand files.

  We tried statprefetch at the end of the stack, as well as right after 
the protocol/client, tried increasing read-ahead, etc.

  Is there anything in particular we should be looking to do, in order 
to get reasonable metadata performance under load?
