What you compiled (configured) using --with-apr is propably not APR but
rather the Tomcat Native Library ( which uses the APR
installation you pointed the configure script to with the above switch.
What I was talking about is the configuration of the configure script
for APR itself.

Tomcat works fine without APR. Therefore the is no *necessity* to use
APR if you want to use Tomcat. APR is simply supposed to improve
performance (moreover with APR you can use OpenSSL certificates with
Tomcat's HTTPS Connector instead of the Java keystore).

Anyway: since you've not configured an HTTPS Connector in Tomcat, I
don't really have an explanation for the slow startup.
