Andrew Purtell commented on HBASE-1771:
---------------------------------------
My write intensive environment (4 node Heritrix crawl farm) has needed this set
to 20 to avoid blocking. Otherwise there are significant troughs in write
throughput at a regular period.
Multithreaded compaction might help.
> PE sequentialWrite is 7x slower because of MemStoreFlusher#checkStoreFileCount
