Anoop Sam John commented on HBASE-17738:
----------------------------------------
The mismatch in #BBs for each thread will be more visible if #threads are
really large. Seems that wont be the case. So its fine with the proposed
addendum way also.
> BucketCache startup is slow

> If you set bucketcache size at 64G say and then start hbase, it takes a long
> time. Can we do the allocations in parallel and not inline with the server
> startup?
> Related, prefetching on a bucketcache is slow. Speed it up.
