Hiya,
I've never actually compiled/installed the APR libraries for tomcat.

What exactly do they improve? I've read that it increases performance in certain situations for production. Tomcat never has it included by default...

so my questions are..
1) When should I compile/install apr?
2) What does it actually change within tomcat regarding performance
3) Is there ever a time when I wouldn't want to install apr?

Cheers,

I looked into it myself. It's such a pain in the that I decided not to go that route.

If you're running a high-performance, high-throughput production server, it's worth considering, but for development servers and production servers that can stand the lower efficiency of the generic Tomcat system, it's more trouble than it's worth to build and install the accelerator.

That's kind of what I always suspected. Thanks
