Eshcar Hillel commented on HBASE-16417:
---------------------------------------
Evaluation results of benchmarks on a 3 machine cluster are attached. Main
points:
(1) in write-only workload ic2 and dc outperform no compaction (with no mslabs)
by 25%. This can be attributed in part to running less GC and in part to
executing less IO.
dc improves write amplification by 25%.
(2) in mixed workload All three options with no mslabs (no compaction, ic2, and
dc) have comparable read latency and throughput. Avg read latency of no
compaction with mslabs is 2.5x than the other options running with no mslabs.
(one run in this setting even failed to complete).
