App freezing and hanging issue while have large code

[akashjasani]

I am editing a large JSON file (~120k lines) in the Code Forge editor with beautification enabled. When I start adding new keys or values, the editor responds very slowly to the first few keystrokes. If I type continuously or quickly, the application becomes unresponsive and freezes for approximately 10–15 seconds.

test_large_body.json
