>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 0.98.13
>            Reporter: Abhishek Singh Chouhan
>            Priority: Major

> 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.
