[6.3/Apache22] Right way to compile worker MPM?

[Gilles]

Hello

	I'm trying to compile the latest ports of Apache22 with support for
the worker MPM so that each child process spawns thread. I'd like to
see if performance improves compared to the prefork model.

Although I checked the "THREADS/Enable threads support in APR" item in
"make config", the resulting binary says this:

# pkg_info | grep apache   
apache-2.2.9_3      Version 2.2.x of Apache web server with prefork
MPM.

Should I edit the makefile file manually to get worked MPM?

Thank you.
