Tomcat with/without Tomcat native library

[Petr Sumbera <Pe...@Sun.COM>]

Hi Guys,

Does anybody have experience or even better some numbers comparing
performance of Tomcat running with and without Tomcat native library
(libtcnative-1)?

I don't see any comparable difference so far (using TC 5.5.23, Native 
Library 1.1.10, Solaris/i386).

Cheers,

Petr

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.

most definitely, the APR connector lets you do keep alive connections on 
more connections than you have threads
and also, biggest gain is of course SSL, OpenSSL vs Java SSL
