Hi all, 

I've made a customization (ps-fn) and works fine in our dev. area. 

My supervisor created a training area which copied everything from the production area. (the information in the training area is same as prod. one) 

When I migrate my project to the training area, everything works fine as in dev. but slow. (I modified the PO-EXPRESS page, everytime when I add / update a PO, it spends 1 min. more to load the page) I've commented all my peoplecode but the problem is still exists. 

How to find out the problem area. 
Please advice 
Thanks 

Regards,

Gerald
