Hector uses tsocket. not sure what you mean by "buffered" - is that framed? Hector by default does not use framed. The code is here if you'd like to have a look http://github.com/rantav/hector/blob/master/src/main/java/me/prettyprint/cassandra/service/CassandraClientFactory.java#L77
<http://github.com/rantav/hector/blob/master/src/main/java/me/prettyprint/cassandra/service/CassandraClientFactory.java#L77>However, I find it hard to believe that the actual connection is the slowing factor. Roughly speaking, cassandra is fast on writes and slow on reads. Exact numbers are per-scenario so it's hard to say, but if you only write and objects are small then from my experience you should expect a few k writes per second on a single host. How much do you see? There are many configuration factors and they all depend on expected usage and available h/w.
