Just a small tips for those trying to run multiple threaded applications on OpenVZ.
Personally I code quite a few multi-threaded applications in Python (as some things are just too hard to do asynchronisely). Very often a 6MB RSS application would eat up close to 100MB of VSZ. As one of the most important metrics on [...]

Bootstraping Low End VPS with Pre-built Scripts
It was fun setting up your very own server. I remembered the time when I received the root password to my very first virtual server back in March 2006 ($22/month for a merely 192MB of memory), it took me hours setting it up to exactly the way I wanted. At the end of the day [...]

Most current Intel and AMD processors can run 64bit instruction sets, and many virtual server vendors are also [...]
Reducing MySQL Memory Usage for Low End Boxes

However the default MySQL installation on Debian/Ubuntu takes around 25MB RSS on a cold-start. Well, not too bad I guess, unless you are running a tight ship with only 64MB of total memory. [...]
Tuning for 64MB Virtual Private Server
Zein: Making the most out of a 64MB VPS — how Ahmed tuned his 64MB Xen VPS from VPS Village to run Lighttpd, PHP/FastCGI and MySQL. He was also trying to get a Ruby on Rails app running but OOM seems inevitable. Great article on getting PHP applications like WordPress running on a minimal VPS.
