If you don't mind my asking, what version of the JDK and JVM were used? My impression of Sun is that they don't worry about optimizing a first release but put a lot of effort into optimization afterward. NIO was introduced in 1.4 and...]]> Fri, 22 Feb 2008 09:30:45 -0500 Fri, 22 Feb 2008 09:30:45 -0500 Fri, 22 Feb 2008 09:30:45 -0500 Feb 22, 2008 Amit Varudkar 1 Re: Erlang YAWS http://www.theserverside.com/discussions/thread.tss?thread_id=48449 2) Is there any reason the JVM couldn't support the same massively concurrent threading as erlang?
