I saw this discussion long time ago, but I couldn't jump to any conclusion on that thread.
Since I'm running my virtual servers under php with fcgid, I guess I should be running apache with worker mpm for better performance.
How do I switch to apache2-mpm-worker without messing anything with virtualmin / webmin?
I was thinking
aptitude remove apache2-mpm-prefork
aptitude install apache2-mpm-worker
Should this be enough?
