Well, to second this, my machine at work is also running Apache with 32 MB RAM. Besides this, it acts as the companie's printserver (including ghostscript), secondary nameserver, my primary X11 display with lots of open applications in various fvwm windows (since i'm too lazy to always close and open them), occasionally the HP scanner program plus the required memory-eating image processing, and occasionally burns CD-Rs in addition to all the load mentioned above (which alone eats up 5 MB of physical memory as a userland cache for safety). Granted, the usual swap allocation is between 50 and 100 MB (out of 150), but i don't see why the pre-forking Apache would cost me too much. I'm also sure i could turn off pre-forking entirely without much troubles, but it just happened to be the default and i figured the costs were not cumbersome. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
