J-BusinessDirectory - site slowed down after installing 4.0

I have no idea what has changed but when i upgraded to 4.0 from 3.6.4 it takes a longer in fact much longer time for the site to load pages. If i load something that is not related to the component it loads reasonable quick. If I click on for example business listings it take forever to load. Just wondering if there is something to fix this or if you could look into it.

Thanx

found the problem. Need to disable joomla sef in control panel. Seems to be issues with this on the joomla 3.3.3 and the upgrade to 3.3.6. Nothing to do with component. Does any one have a solution to getting sef to work with out the native one in joomla. I tried mijosef but it froze my site and I have to do restore.
