I did add the value you recommended but the behavior didn't change.
I still get 100 api request per second after I apply the settings.
What I noticed it's only on my Windows 10 machine with "8gadgetpack" installed.
Maybe that's the reason for the strange behavior?
It's hard to say without more data what causes this, but after applying settings, gadget simply can't send that many requests. It will send only one request to a single API, unless you have configured to call a single API for multiple things.
How do you detect those 100 API requests, and which API server is spammed?
How many gadgets do you have open?
What settings are you using (especially URLs)?
