While investigating a large descrepancy between query time ( 243 queries taking roughly 37 milliseconds) and total page execution time ~390 millisecond, I looked at various filters I have installed. I noticed video filter module added a significant overhead and by disabling it was abale to reduce the page execution time to ~212 milliseconds. I also opened an issue for the module here http://drupal.org/node/375415 and you can see more details about my test.
I already use APC.
Are there other filters or modules that you aware could add significant overhead to page execution time?
