I wonder how many products a Catalook can handel, front for users is fast, but try to make a changes as admin on a product is slow at least you have to wait voor 25 seconds.

I can't be the server thats for sure it has 4 cpu 12 gig internal memory

Some one have a answer?

Make sure you are using Ajax and Telerik CDN in DNN 7 and CSS and Javascritp are minified and merged in CLient Resource Mamanegement and then should fly
