Not great, much slower than the jolokia 1.2.3 client. So i think there must have been a performance
degradation in jolokia. I have a ticket open on the jolokia github repository to talk about
the issue. We ended up being able to work around the issue by upgrading to the master version
of the diamond jolokia collector and kept the updated jolokia agent which seems to have resolved
to issue.

Thanks so much for your help. I think we can close this issue as not a problem, It'll be good
for people to be able to search for posterity.

> I am seeing some very slow jolokia request times on my Cassandra 3.0 cluster. Specifically
when running the following:
> {code}
> curl 127.0.0.1:8778/jolokia/list
> {code}
> on a slightly loaded cluster I am seeing request times around 30-40 seconds and on a
more heavily loaded cluster I am seeing request times in the 2 minute mark. We are currently
using jolokia 1.3.2 and v4 of the diamond collector. I also have a Cassandra 1.1 cluster that
has the same load and number of nodes and running the same curl command comes back in about
1 second.
> Is there anything I can do to help diagnose this issue to see what is causing the slowdown
or has anyone else experience this?
