Hi Tom
We're running our WeBWorK servers on Sun Solaris machines. In that environment each running httpd process for a non-mod_perl apache install takes about 8MB of memory. For a mod_perl httpd process they bulk up to between 10 and 16MB. On another system your numbers may vary, but it should be possible to get an estimate for the required memory by looking at (MaxClients)(hhtpdProcessMemory) + (other services' requirements) + (memory needed for the OS). For further comparison, for my servers Solaris 8 requires about 170MB and the other services I have running need between 400MB and 500MB. So, as an example, to allow a maximum of 100 clients (httpd processes), between 2 and 3GB would be reasonable for us. I'd expect Linux to have a smaller memory footprint than Solaris, however.
I hope this is helpful |
