Drupal slow when saving nodes (content, comments, admin ...)

Drupal slow when saving nodes (content, comments, admin ...)? Maybe the problem is really simple, try to deactivate some modules that you don't use. It is common to test modules that you finally don't use in your production server. Search for them and deactivate, they take a lot of memory, even if you think you are not using them.
