Eshcar Hillel commented on HBASE-16417:
---------------------------------------
Number of regions in all experiments is 50.
Figure 3 compares default memstore with mslabs (blue column) and without mslabs
(purple column) in a PE run with write only workload uniform distribution. Here
are the absolute numbers:
|| write latencies ||MB/s||50th||75th||95th||99th||99.9th||99.99th||99.999th||
|no compaction|207.2| 57.3| 60.1| 80.7| 9608| 55362| 162462.6|
816825|
|no compaction (no mslab)|207.88| 57.0| 59.9| 85.2| 9496| 55521|
167699.7| 933907|
Figure 6 compares default memstore with mslabs (blue column) and without mslabs
(purple column) in a YCSB run with mixed workload zipfian distribution. Here
are the absolute numbers:
|| read latencies|| op/s|| #gc|| avg|| 50th ||75th|| 95th||
99th||
|no compaction| 5673| 7693| 3596.0| 2109| 3061.0| 4303| 5535.0|
|no compaction (no mslab)| 7900| 6601| 2586| 2137| 3027.0| 4163|
5211.0|
I can re-run the benchmarks if you believe this is in contradiction with your
previous findings. But the HW is different and might affect the results.
