I'm currently importing a productfeed of about 4000 products. The products are phone accesoires. For example you have a general mini-usb cable that work for almost all phones. That product will get insert in the following categories:
etc for all models that the mini-usb cable works for
And that's only 1 cable, I have hundreds of phones and thousands of products. I've only imported 600 products and to load the store page WordPress already does 3500 queries to the database.
What's the best way to proceed in this situation?
