Liang Xie commented on HBASE-9669:
----------------------------------

i just say "one of" :)    the largest contributor is  block lru cache or memstore depends
on user's configuration.  yes, i just refred to bucket cache with off-heap mode enabled.

> After lru block off-heap, the bloom filter is becoming one of the largest contributers

gc hurt.
