zhangduo commented on HBASE-8329:
---------------------------------
add a testcase to test compaction speed locally.
The result is
{noformat}
Test with rowSize = 16 B, size = 358.29 MB, duration = 8802ms, rate =
41682.69917792121KB/sec
Test with rowSize = 4 KB, size = 1.21 GB, duration = 25054ms, rate =
50831.594965811346KB/sec
Test with rowSize = 512 KB, size = 1.25 GB, duration = 32501ms, rate =
40347.30749270215KB/sec
{noformat}
Seems even with a small value size we can still get a 40MB/sec rate...
