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.
The apache ab tool can be used to test your server: http://httpd.apache.org/docs/2.0/programs/ab.html I think its not enough ram for this setup, but you will see.
