OK, this is a catalog not a shopping cart.
I think you need to turn off buffering so that the web server sends stuff
out as it gets it. It appears to be waiting for the full page to be built
before it sends anything. Its a php system so a PHP expert should chime
in with how to do this.
I suspect the category system which is listing the number of products on
the left is taking a lot of the time.
How do you link your products to your categories? I suspect you will need
to add a column in the category table to list the number of products so
you are not doing a select count(*) Products under Category X each time.
If your select to list the categories is also doing the count then you
might want to try separating that out (two select's). Without your table
structure I'm shooting in the dark a bit here.
Just a few thoughts. Luck.
The shopping cart is not the issue, the category list on the left is, I
