Subject [jira] [Created] (HBASE-14352) Replication is terribly slow with WAL compression

----------------------------------------------

             Summary: Replication is terribly slow with WAL compression
                 Key: HBASE-14352
                 URL: https://issues.apache.org/jira/browse/HBASE-14352
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.98.13
            Reporter: Abhishek Singh Chouhan


For the same load, replication with WAL compression enabled is almost 6x slower than with
compression turned off. Age of last shipped operation is also correspondingly much higher
when compression is turned on. 

By observing Size of log queue we can see that it is taking too much time for the queue to
clear up.

Attaching corresponding graphs.
