ryan rawson commented on HBASE-2941:
------------------------------------
Doing some testing on this, using ycsb as a read load generator (gets), using
50 and 200 threads client side, with the patch from HBASE-2939, I am showing
all sorts of great improvements:
- the latency curve slides inwards
- the average request time goes down from .4-.8 ms
Overall it's a huge huge win. I'll attach the XLSX that has graphs and data
from my runs - 8 sheets in total.
> port HADOOP-6713 - threading scalability for RPC reads - to HBase

> HADOOP-6713 has patch to fix the read scalability of hadoop rpc. Right now
> a single thread accepts() then receives the RPC payload for every single RPC
> in hbase. Including object creation, writable deserialization, etc.
> Apply the patch from that issue to our own forked HBaseRPC code.
