[~abhishek.chouhan]
I would like to know how to interpret the size_of_log_queue.png.  The y axis is 
the size of the queue and the time to taken to clear the queue has some 
difference on or before Aug 25?  Am i reading it right?

> Replication is terribly slow with WAL compression

> 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.
