I checked through all the logs last night for that domain, and the main apache log and didn't see any errors. But also didn't see a lot of 200 codes. A lot of 304 codes though. And yes, it is very slow loading. But the server load is low and other php generated pages I checked load normally.
If there are any addons, modules?, not sure what Wordpress calls their addons, maybe try disabling them one at a time.
A stock install doesn't seem slow -

mysql has a few entries in the error log every few days having to do with databases not found (not that domain though).
Prior to the data center changing the power source 4 days ago it was up about 100 days. I just updated the kernel 4 days ago as well, and rebuilt Apache/php to see if that would help anything. Prior to that nothing was changed the last 100 days. You're correct that Fantastico is slow but it only seems slow in the XController theme for some reason. And cpanel, whm, fantastico uses a whole different installation of apache & php.
I still suspect its an addon but you may want to clean up the database and make sure all the tables are repaired and optimized.
This is from the html code on your page -

This is from the html code on the example WP I installed on that same server:
