Description Pranith Kumar K 2015-12-10 06:49:40 UTC 
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.
