That kills your performance always. Could you run your test on a different machine or temporarily switch off the regular server?

But even the non-modperl servers at 30 Mbyte size seems ridiculously large: are you sure you need all the modules that you compiled into Apache? Elizabeth Mattijsen

It looks like you have some code that hogs memory, and you'll need to control it somehow. Most people have servers more in the range of 10-40MB, with a bunch of that shared. - Perrin
