Hi mstuart
We are aware of the performance issue of the Ajax Filters plugin. It appears when you have more than a thousand products with many specification and attribute options in a single category. At the moment we are working on improving the performance of the filters and we will let you know as soon as we are ready.
It is a good suggestion to add "apply" button to the filters to apply a selection. Can you please add this to our
User voice portal, so that other clients can see it and vote.
For the moment I suggest to reduce the number of products in a category to 200-300 and not include products from subcategories.
Best wishes,
Ivan Stoyanov
With the release of Nop Ajax Filter 3.0, has the performance issues been fixed?
