Well, for my part I definitely like the "take a profiler and optimize the
things that need to get optimized" approach more than the "optimize by
best-guess" approach. Plus from own experience I know Java is *not* slow.
People frequently confuse JRE startup times and Swing performance with the
overall Java performance.

Additionally, I don't think really performance is an issue (at least with
the transports) right now. When I started working on AIM-t, there were
several errors in it that kept it crashing even in small environments. Now
there are only several memory leaks left ;-).
