Pre-2.0.3, there was no option to turn off Nagle's algorithm. We introduced this in 2.0.3 and are debating whether this needs to be made the default, since it involves altering a default behavior :-). We will certainly consider making this the default behavior in our upcoming releases. Thanks, Vijay
