Randy Fox commented on HBASE-14624:
-----------------------------------

As a baseline (and to install the patch) I did a rolling restart of one RS and 
it took 7 minutes to move the regions.  i waited a few hours for bucket cache 
to fill up and then moved all the regions off and it took 20 seconds or so and 
I verified the buckets freed up.

> BucketCache.freeBlock is too expensive

> Moving regions is unacceptably slow when using bucket cache, as it takes too 
> long to free all the blocks.
