Subject High CPU Usage with Apache Portable Runtime
Date Wed, 20 Sep 2006 17:58:14 GMT

I am noticing high cpu usage with tomcat 5.5.12 using APR 1.2.7 that 
doesn't appear with tomcat without apr.
The server is a Solaris 10 x86, bi processor.

As soon as several ajp13 connections are made, the cpu usage of the java 
process increase to 50%.

Is this expected behaviour ? Is the use of a socket poller the cause of 
this cpu usage ?
