Kirubakaran Pakkirisamy commented on HBASE-9410:
------------------------------------------------
Ofcourse the latency is affected by the number of regions of the table and the
total # of regions being used on the server. I expect a degradation, but not
exponential.
> Concurrent coprocessor endpoint executions slow down exponentially
