I have created a small Drupal 7 website for the company I am working for. It has less than 30 pages, not a large number of extra modules, and is low traffic. But it is so slow at times, 20 seconds - 5 minutes for load times. I haven't been able to get help from support, because its fast when they check.
I've spent way too much time trying to figure out how to make it faster, and am getting no where. The Drupal Troubleshooting wiki page stuff seems obsolete. I've been turning things off and on in the Dreamhost Web Panel domain settings, without any effect. Does anyone know what the best settings are for PHP version, web security, page speed optimization, etc?
