Powell Molleti commented on ZOOKEEPER-1000:
-------------------------------------------
Updated the read-me with benchmark. Posting summary here:
A 3 Server ensemble running in a single VM, command used(single client)
zk-latencies.py --cluster
"127.0.1.1:2181,127.0.1.2:2181,127.0.1.3:2181"--znode_size=100
--znode_count=10000 --timeout=5000 --watch_multiple=5
SSL Disabled:
110000 ops took 16441.6 ms
SSL Enabled:
110000 ops took 16721.2 ms
>From my understanding SSL support will have measurable impact in connection
>setup latency hence CPS bound application will suffer. Due to widespread
>AES-NI support on CPUs (and Java supports this) I am not quite certain w.r.t
>latency added for steady state data transfer's encrypt/decrypt process,
>potentially impacting ZAB. I was hoping that any such measurable latency might
>show up in smoke tests which were run the past. Let me know if you other perf
>tests in mind that I can focus on next to get more insight.
I am running into limits of single VM, I would like to run with more clients to
replicate past tests
> Provide SSL in zookeeper to be able to run cross colos.
