Hi!
Thank you for the details. The issue was caused by a minor misconfiguration only, where the exact matching was enabled and thus the index table was not in effect, I turned it off for you: https://i.imgur.com/OUktF1N.png
The performance has improved over 50x faster on the server side: https://i.imgur.com/61LWtJt.png
..as well as the requests should be around 1-2 seconds on the client side, I made a few measurments to make sure it is okay: https://i.imgur.com/GJs2Dws.png
It should be all right now.
