Hello Bo,

While mod_php will be faster, I suggest you setup suphp as the php handler, it will be cheaper on ram and more secure as the php scripts run under the owner of the file while mod_php executes every php script under the same user.

Nginx as a reverse proxy works great and doesn’t consume much ram

Hi, my server is running out of memory. There’re so many php-cgi processes and they’re still there for a long while after serving requests. I’m consider using mod_php instead of mod_fcgi and nginx in front of apache as a reverse proxy to handle static files. Is that a good idea?

180MB is more than enough
you can configure the allocation size

The site was running over Fast-CGI, yesterday I install apc extension and it helps a lot, with an apache max threads reduction and a mysql connections little optimization now I’ve good load, about 0.6 average and about 180 MB free ram.

I’ve memcache installation on the TODO list. Is it consume a lot of ram? will be enough to 180 MB free RAM I have left?

Next month i will install a new wordpress site.

Thanks for everything.

since you're running only one site on your server caching is the solution as cracklight mentioned and with 512mb of ram you can cache a lot

no need to run your site through suphp, switch to Fast-CGI instead
optimize mysql to cache more (I believe this will lower your load significantly)
reinstall eaccelerator(if you unistalled it) or apc
also have a look at memcached

I suggest to use page caching. Try apc or something like this. Personally I run nginx + fcgi with 512M and 1/2 Core and seems ok.

I’m running on a vps with 512MB RAM, only 600 MHz processor, it’s a very low end vps.

Only one domain with php and mysql but with a lot of traffic, 4-6k page views average per day.

Now I disable postfix, amavis, clamav and spamassassing completly, at the moment I don’t need mail server.

also give us the results of

cat /proc/cpuinfo | grep MHz
