Zheng Hu commented on HBASE-21459:
----------------------------------
[~stack], I made two test:
1. benchmark the checkKeyValueBytes() method by using JMH framework to
exclude the JIT's impact. the result is here:
https://issues.apache.org/jira/secure/attachment/12949680/jmh-testing.log . I
think we can mainly focuse on the last part in the result, it means the avg
time cost after call the checkKeyValueBytes multiple times (diff rowKey,
tagSize, valuleLen etc..)

2. benchmark the checkKeyValueBytes method directly by using patch [1], the
result is here: [2]. Also indicate: in diff cases (rowLen, valueLen, tagSize,
rowSize), the avg time cost (ns/op) after call the method multiple times.
Currently, I'm focusing on testing the single method, not by starting cluster
with the validatation patch or without patch... I think the single method
performance is enough to proof that it has minor impact on the read/write
performance. Thanks.
