ramkrishna.s.vasudevan updated HBASE-17738:
-------------------------------------------
Attachment: HBASE-17738_6_withoutUnsafe.patch
Patch that splits the buffer creation based on the number of threads and
creates only those many callables as the number of threads. This one and the
previous patch both takes 11 secs only. How ever before the patch it was taking
34secs.
The previous patch was easy to read and this has certain index manipulation to
be done.

> 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.
