Hello.
We are using java async thrift client.
As of ruby, it seems you need to use something like

(Not sure as I know nothing about ruby).

you're doing that? Which client?
Because even with 3 concurrent client nodes, my single postgresql server is
still out performing my 2 node cassandra cluster, although the gap is narrowing.

Note that having tons of TCP connections is not good. We are using async
client to issue multiple calls over single connection at same time. You
can do the same.

Ok, so you think the write speed is limited by the client and protocol, rather
than the cassandra backend? This sounds reasonable, and fits with our use case,
as we will have several servers writing. However, a bit harder to test!

Hi Jeff,
Writing serially over one connection will be slower. If you run many threads
hitting the server at once you will see throughput improve.
