My M1 site consists of 30k products and 100's attributes.

Attributes like authors,edition,publisher etc.

After successfully migrated to M 2.3.4 If I click category links and left navigation filterable attributes to take too much time to apply filter.

How to increase the speed of category links and ajax filterable attributes?

Any help thanks.

Try to improve speed with Website optimisation. Make sure you have merge CSS and JS provide by Magento 2 Feature and also set Production Mode enable.

  • After merging CSS and js still category & attributes takes too much time to load. If i click category, it takes 120 seconds takes to display the page.
