This is difficult to answer because it will depend on what you are doing
with the server.
But at least, a good connection with the server is important with the
smalest latency. The client makes a lot of small request to the server
so it can become slow if the latency is too high.
I have made some improvement regarding this issue on the trunk.
Otherwise, there were a lot of work done in the between 2.0 and 2.2 to
reduce the memory usage.
