Sergey Shelukhin commented on HBASE-10138:
------------------------------------------
I ran 5 iterations on my laptop in highly unscientific way...
GaussianRandomReadBenchmark may be slightly slower, and
UniformRandomSmallScanBenchmark may be slightly faster, but it could be noise.
Do you suggest more rigorous testing?
> incorrect or confusing test value is used in block caches

> DEFAULT_BLOCKSIZE_SMALL is described as:
> {code}
> // Make default block size for StoreFiles 8k while testing. TODO: FIX!
> // Need to make it 8k for testing.
> public static final int DEFAULT_BLOCKSIZE_SMALL = 8 * 1024;
> {code}
> This value is used on production path in CacheConfig thru HStore/HRegion, and
> passed to various cache object.
> We should change it to actual block size, or if it is somehow by design at
> least we should clarify it and remove the comment.
