Nicolas Liochon commented on HBASE-11564:
-----------------------------------------
Comparing the results with PE reads, 1m rows, 3 replicas and a 100 microseconds
delay gives:
- w/o the patch:
- total: 210s
- 95%: 426us
- 99%: 550us
- with the patch:
- total: 174s (i.e. w/o the patch we're 20% slower)
- 95%: 208us
- 99%: 262us
So it's nice. I still have some variation in the results so likely there is
still room from improvement somewhere.
Commit is on its way...

> The current client code depends on interrupting the thread for canceling a
> request. It's actually possible to rely on a callback in protobuf.
> The patch includes as well various performance improvements in replica
> management.
> On a version before HBASE-11492 the perf was ~35% better. I will redo the
> test with the last version.
