Finally, after several weeks of thinking about it, I removed Apache 2 from my server machine and replaced it with lighttpd.
I don't have anything against Apache. In fact has never gave me any problem. But, in a VPS environment, RAM memory is the main resource to save. And Apache is so RAM hungry (besides MySQL), that the server was almost Apache dedicated.
After searching for a viable alternative I came to lighttpd. Small, low memory footprint, super fast, support for virtual hosts, php, fastcgi. Well, this blog is already running over lighttpd/fastcgi.
Then only drawback was, lighttpd has no support (complete as today) for Web DAV, so Subversion couldn't work with https, but as I am the only user for my repo, I now use svn+ssh to access it.
So, the migration was OK.
Hi,
Have you looked at Nginx ( http://wiki.codemongers.com/Main ) ?
If you're looking for something _very_ light, it could be interesting to investigate further in this direction :p
Yes I have. In fact my list included lighttpd, nginx and thttpd. thttpd was discarded because of the documentation didn't look appealing :). I finally chose lighttpd because the code to enable FastCGI/PHP in lighttpd was just a couple of lines in lighttpd.conf and in nginx it was several lines (http://wiki.codemongers.com/NginxFcgiExample). Furthermore, nginx needed span-fcgi, a program included with lighttpd. So instead of installing lighttpd and nginx to use nginx, I used just lighttpd.
A practical soluction more than a technical one, as you can see :)
