json-opening

This is a big problem for me, I have a JSON file for liquibase, this is a changelog file with the liquibase syntax to update the database. The file is round about 55kb big, has 110 lines and has a lot of insert objects inside of it. It tooks round about 5 seconds or so to open the file and to interact with it and to scroll. It hangs when I scroll for a few seconds.

I added snapshots for opening the JSON file (json-opening) and a snapshot for scrolling inside the JSON file (json-scrolling)

If the json file needed, I have to change the content inside of it.


Regards

Chris
