I don't think you can have a nbio connector with a compliant servlet
container, because the J2EE spec mandates at the moment: 1 thread <-> 1
request.

My opinion on the nbio issue:
I completely agree with Remy, the IO is not the issue at least
for the current code and the near future. The char-byte
conversions are far more expensive.
JDK1.4 provides a very nice solution for the char conversions,
however my tests show it to be comparable in spe

It depends. Using NIO, you can serve static content as fast

The 63 channel limit is a Windows-only bug in the Beta,
designing code around it probably isn't a good idea.
