Hi Thomas, I wanted to see your patch but it does not work against trunk right now. Could you please upload again?

> When profiling graph computations running on HAMA it turned out that huge amount of time is spent in RPC calls.
> To reduce this overhead I propose extending the GroomServer's API with a put(BSPMessageBundle) method so that a group of messages can be transferred from the caller to the callee at once. Also, the sync() operation should be improved by sending messages in batches rather than one-by-one.
> Using BSPMessageBundle makes it easier to add support for compression of messages later.
