Optimizing a low end Debian VPS for lower memory footprint
I've got a low end VPS with 128 mb RAM and Debian Wheezy on it. I use it to host static content with nginx and a Multi Theft Auto: San Andreas game server.
I'd like to optimize it as much as possible, so it does only what I need and doesn't waste resources on unnecessary stuff.
I've already tried disabling certain services from startup, also removed some packages suggested by deborphan. The usual memory usage (subtracting caches and buffers) oscillates around 20 mb when there are four players on the server.
Could you help me to further optimize the machine? I can provide anything needed.
