------------------------------------------------
Yep...both of them had compression enabled.
> 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
> Attachments: age_of_last_shipped.png, size_of_log_queue.png
>
>
> 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.
