xojo.net.HTTPSockets Page Received high CPU usage

Having an issue waiting for a response from a website.

The app is a web app, running on Linux.
The CPU goes to 99% when waiting for a response.
Using Xojo 2019, xojo.net.HTTPSockets

I have a While Loop that awaits for the page received.

I did not use the Sleep(2000) command, but I see that may be an option.
