As you may know, I have mostly used CentOS or Scientific linux on my servers. I have decided to try running a site on a Debian server and things seem to be going well so far.
This site is currently running on a 128mb OpenVZ VPS from tinyvz.com which is part of Ramhost. The memory use seems to be about the same as it was last time I used an OpenVZ based VPS for a webserver. Disk usage is a little lower than my standard Scientific Linux/CentOS setups.
