Hi

I have a VPS that it works for Drupal 6 very fast but in drupal 7 it's very slow.
I read the System requirements page at drupal official site and matched VPS config with the configs wrote there, but the problem was not solved.
links for test:
drupal 6 (works good) : http://moshavereh.porsemani.ir/
drupal 7 (works very slow) : http://amlakema.ir/
my VPS info:
PHP Version 5.3.21
MySQL version: 5.5.14
SERVER_SOFTWARE :Apache/2

Please help me.
thanks

To state the obvious, there are more differences between those two sites than the Drupal version. The themes are different, and probably different modules are in use. One can't tell by looking from a difference, but the caching settings could be different, and a load of other things.

So the first step is to find out whether the Drupal version is the issue. Create a simple test installation of Drupal 6, and stick to Garland. Do the same for Drupal 7, and change the theme for Garland. By all means add modules like Views etc., and add content, but make sure you do the same for both sites. Is the D7 one noticeably slower than the D6 one?

If not, then try tweaking the slow site. Get rid of the custom theme first. Disable modules one by one. Until you find what's causing the slowness.

Hi
You could install the http://drupal.org/project/devel module which has some excellent functions to help debug performance issues.

Hi!
Visit my post about best drupal 7 apache config!
http://drupal.org/node/1940584

After you finish apache installation and config, Increase php_memory_limit least 256M in php.ini

Then, turn off unused modules, clear all caches, run system update, rebuild premissions, run cron.
For the faster operation, use administration menu and module filter modules.
