Well a browser is basically a sandbox for a webapp.
To debug something complex, I would use chrome devtools, which can measure all kinds of metrics, and the function "Audit > LightHouse" automates the process and ranks a webapp in several key categories.
This case would appear to be related to network requests, so that issue should be fairly obvious in LightHouse.
