Optimizing an application is often not very easy, especially for a novice user. However there are always some useful things you can take into account and boost the quality of the performance of your online shop. Here are some we can share about ZenCart:
1. Optimize your database. You can check how here
2. Reduce the number of products on your main page
3. Turn off Category Counts from the ZenCart Admin Backend:
– Configuration
– My Store
– Show Category Counts
Doing any of those simple things can reflect on a better performance and customer satisfaction for your shop.
