All requests on a D6 (latest) site, from simply viewing a page (cached), to performing an administrative action, to running a drush command, are painfully slow.
It took about 12 seconds to load the homepage from a remote location today; 1-2 seconds is normal for static content, and 3-5 for java generated dynamic content, for non-drupal areas of this apache2 installation.
I disabled the nodetype module via drush (took about 25 seconds to give me the confirmation prompt).
It is now taking 5-8 seconds to load each administrative page. The slight speedup suggests that modules are potentially causing the issue here.
I have attached a module list from drush, but is there anything else i should be looking at on the drupal side, to provide some kind of speedup?
JS optimization is enabled; CSS optimization is not. Caching is standard (block caching enabled but may not be being used). I am currently trying page compression; it was previously disabled.
Thanks for any ideas.
