On Solaris there wasn't a big difference last time I profiled it. On
Solaris, it doesn't cost much to have a large number of threads blocking on
input, so you don't get a lot from the APR Poller. Also, the Solaris JVM is
pretty optimized for the OS. From testing with the AJP Connectors, you
might have noticible improvements with TC 6 and the NIO Connector on
Solaris, but I haven't profiled it myself.

It's with Linux boxes (I haven't seen reports for other *nixs) with older
kernels that you see the most improvement when using the APR Connector.
