Description Ben Turner 2015-03-16 20:41:08 UTC 
Description of problem:

Metadata, specifically ls -l performance has been greatly reduced on replicated volumes with 3.0.4.  I do not see this perf hit on distributed volumes, and perf on replicated 3.0.3 volumes is good.

Version-Release number of selected component (if applicable):

glusterfs-3.6.0.51

How reproducible:

Every time.

Steps to Reproduce:
1.  Create 10k files
2.  Clear buffers and cache on both servers and clients
3.  Run ls -l on files

Actual results:

Perf hit vs 3.0.3.

Expected results:

Perf within 10% of 3.0.3.
