However as a general statement Cassandra is highly multi-threaded. Threads are assigned within thread pools and these thread pools can be thought of as a type of processing pipeline, such that one is often the input to another. When pushing Cassandra near its maximum capacity, you will therefore spend a lot of time switching between threads. =Rob http://twitter.com/rcolidba
