Long Execution Time on Big Site

Permalink
I've got a fairly large Concrete5 site with 1700+ pages. I recently upgrade to 5.6.0.2, and since upgrading have been experiencing slow load times on the homepage.

I've adding a bit of PHP that is calculating the execution time of each page, and on subpages I'm getting anywhere from about 0.1 - 0.5 seconds, which is fine, but the homepage is typically showing up around 3-5 seconds. The homepage is utilizing a different template, but there's nothing within that template that would cause a significant increase in load time. I've also removed all the blocks from the page, so it doesn't seem to be an issue with the blocks either.

Any ideas as to what would be causing this? Is there something different in the way C5 renders a homepage (cID=1) vs. every other page?

I think I have a solution that has helped. Lots of useful information in this thread:http://www.concrete5.org/community/forums/usage/concrete5-horribly-...

Particularly, this:

define('CACHE_FRONTEND_OPTIONS', serialize(array('automatic_cleaning_factor' => 0)));


After adding this to config/site.php, of my last three tests on the homepage, none have been over .2 seconds.
