Hi
We've recently done some testing with a 3.12 disperse cluster. The performance of filesystem stat calls was terrible, taking multiple seconds. We dumped client side stats to see what was going on and noticed gluster STAT was the culprit. tpcdump shows a STAT call being sent and replied to quite fast, but still the client hangs for multiple seconds before returning.
After downgrading client side to 3.10 (servers still being 3.12), stat calls return instantaneous. After dumping client side stats when running the 3.10 client we noticed that the linux lstat gets translated to a STATFS instead of a STAT.
Has something changed to cause this behaviour? Is there some additional tuning that needs to be done when running 3.12?
