Vikas Vishwakarma commented on HBASE-17877:
-------------------------------------------
[~adongre] I basically used guava UnsignedBytesBenchmark based implementation
for the benchmarks running them against different comparator implementations ,
different byte array sizes, etc .. only difference is to use randomized byte
array inputs instead of changing just the last byte else the results are
impacted by compiler optimizations
