I learned the hard way, that running py_stress in the src/contrib directory
is a great way to test what kind of speeds you are really getting.
What tools / client are you using to test to get the 200ms number?

Really interesting find.
After Jonathan E. suggested py_stress and it seemed clear the problem was in
my .net client I spent a few days debugging the client in detail.
I ended up changing my CassandraContext instantiation to use a
TBuffferedProtocol(TSocket) instead of a
TSoc
Any pointers on why a thrift client would fly against cass on one os vs
another? The only delta is os.
I'm going to try py_stress remote.

Sounds like the problem is with the C# client code, then.

e machines,
so I can compare the two for speed, because either I’ve got crap for
hardware, or there is something rotten in Denmark.

A friend and I have each setup a few Cassandra stand alone nodes, completely
