Asankha C. Perera resolved SYNAPSE-86.
--------------------------------------
Resolution: Fixed
Fix Version/s: 1.0-RC1-B3
Fixed by using virtual buffered pipes' instead of the windows socket pipes. No
change for Linux/Solaris etc, and these would use the default nio.Pipe
implementation of the JDK through the native calls
Will test this through JProfiler later once I get time
> Overcome resource limitations in Windows systems due to use of Pipes when the
> NIO transport is used under load

> On Windows Systems the java.nio.channels.Pipe implementation
> (sun.nio.ch.PipeImpl) uses a socket connection which is both expensive and
> resource intensive. This causes TCP ports to be exhausted when the NIO
> transport is being used under load. Linux and Solaris systems optimize this
> to native calls.
> However, Synapse NIO transport must be able to perform well and unhindered
> even on operating systems like Windows ;-)
