Description Krutika Dhananjay 2016-09-02 11:29:52 UTC

+++ This bug was initially created as a clone of Bug #1290304 +++

Description of problem:
In the unoptimized version of transaction we have: 1) Lock,
2) Pre-op 3) op 4) Post-op 5) unlock
With compound fops we will have:
1) Lock, 2) Pre-op + op 3) post-op + unlock
This reduces round trips from 5 to 3 in the un-optimized version 
of afr-transaction.

This helps in small file write workload.
Version-Release number of selected component (if applicable):
