Hiii ! looking for some guidance to improve the page sped 
I am currently creating a large number of static collection pages, but I have noticed that these pages load very slowly.
After investigating the cause, I found that the data is being loaded from a JSON file, and the JSON file itself is quite large. I assume that a separate JSON file is being created for each static collection.
If we were to split the JSON files into smaller parts (as currently, a single collection contains a large amount of data), would this improve the loading speed?
Or is there another recommended approach to optimize performance?
I appreciate your guidance.
