Yifan Cai updated CASSANDRA-16343:
----------------------------------
Test and Documentation Plan:
Perf. Test Plan
# Run data prepopulation for both 3.0 and 4.0 clusters. 200GB per node.
# Run steady state load for X seconds and compare the compaction performance.
The workload used in the test was generated from tlp-stress.
Steady state load, Write : Delete == 4 : 1, and the QPS was kept at 1500/s.
Status: Patch Available (was: Open)

The compaction performance comparison mainly focuses on the compaction related
metrics, e.g. compaction throughput, pending tasks, etc. Query latency is *not*
compared, since is can be affected by many other components that changed
between 3.0 and 4.0.
Under the same load, both 3.0 and 4.0 clusters show a similar compaction
performance for STCS. The compaction in 4.0 runs slightly more actively.
Details can be found in the report linked above.
