Very high ram use in Ubuntu compare to debian

Posted on August 11, 2013

hi. I had a Debian 7x64 server that had some security issues and because I’m more familiar with Ubuntu turned to Ubuntu 12.04x64. both my droplets was 512 and served one WordPress site with apache/mysql

In Debian my ram use was basically between 130 and 350 mb and never passed 400mb In Ubuntu my rame use is between 179 and 470 and even swap use more ram

is this normal? because the website is new and only have 100 500 visitor/view a day.

I believe Ubuntu uses more RAM than Debian by default. Try switching to nginx instead of apache: https://www.digitalocean.com/community/articles/how-to-install-nginx-on-ubuntu-12-04-lts-precise-pangolin http://codex.wordpress.org/Nginx#Per_Site_configuration

tnx for your fast response that’s the third year that I uses apache and I’m really familiar with it’s security options. nginx will be a new world for me specially with the site is being more popular I can’t risk a change. I checked with Webmin and as u said apache is using 300mb of ram. It’s strange because apache is the same in both debian and ubuntu a I think of course

Try switching to http://httpd.apache.org/docs/current/mod/worker.html and php5-fpm instead of mod_php: https://www.digitalocean.com/community/questions/how-to-install-php-fast-cgi-in-ubuntu-12-03-apache-t
