Hi,
There is lots of information available for how to split resources between containers for a given hardware node and how to use user_beancounter to monitor requirements but I can't find much about recommended configs for different types of containers.
I've just tried to set up Apache/MySQL/PHP on a external hosted VZ for which the UBC values can't be changed and am getting lots of kmemsize failcounts. If I reduce the number of Apache processes I then get lots of tcpsndbuf failcounts.
Does anyone have any recommendations for what is feasable for given UBC values? If Apache/MySQL/PHP is not possible on the VZ I've got I'll give up now and buy one elsewhere.
I've included my user_beancounters output below.
Thanks,
Gabriel

I think what you're asking is impossible to specify. You can take a template, happily run Apache with a small static site and have it work well for the next five years. And you could take the same template, start up Apache & Tomcat and max resources out just by starting the services.
I guess one could only come up with some general numbers trough methodical testing, ie. one could specify that one needs at least this much resources to:
- start up apache with php and a mysql server on SL 6 stock template without any visitors/users
- start up the same config with stock Wordpress added, without any visitors
- start up the same config and serve 10 concurrent Wordpress visitors
- etc. etc.
But than you take that stock Wordpress, install a custom theme, a plugin or two, add one or two .js scripts and... kaboom. Your resource needs are completely different.
Same goes for OS settings. Give me a stock openvz SL6 template to start with and about 20 seconds and a couple of conf file edits later, my VPS will use a completely different amount of resources than it used to.
So, my advice would be - choose a provider that can offer you good support, clear line of resource upgrades if your site grows, etc. That's pretty much all you can do.
Then set everything up as good as you can, test your OS template and code and see how much resources you really need.
