Hi there... I am coming from a Windows server background - slightly new to linux. Anyway, I am running Debian 4 on a VPS with the following spec: - 384 MB RAM - 15 GB Disk (This is fine for my requirements) - Upto 2 IP Addresses - 150 GB Bandwidth (More than enough for my sites) All the above is fine for my requirements except I am unsure about the RAM. Is this going to be enough to run 2 x-cart websites - which have max 10 - 15 people on the site at any one time making a purchase? In my testing so far I have been receiving "FATAL ERRORS: out of memory" so I have increased the PHP max memory to 228 MB - and I don't seem to be getting these errors at all anymore. However, is there a way I can stress test my server simulating 20 users on the site for example? I understand Linux can run with a lot less RAM than Windows since it does not have the whole desktop GUI thing to deal with...am I right in thinking this VPS is fit for my requirements? Should I take other steps to limit the use of resources so that a planned error message could be displayed instead of allowing any amount of users until the server actually crashes? thanks in advance.
