As of Jan 25 2024 the high CPU usage problem in the web browser appears to be solved. At least on macOS Safari on am arm64 Mac the CPU usage of the opened and active Zendesk window is only about 1%. Only during user activity in the window it increases to 10 - 20% temporarily, but that is expected for any interactive web app.

Maybe it was related to the old Apps API which was switched off on January 10, 2024 as announced in https://support.zendesk.com/hc/en-us/articles/5500321965978 and we had some of them active.

The 20% CPU usage (of all 6 cores on the Macbook) is also the magnitude I usually saw on Chrome for the agent pages, often even more, up to 25%. That's why I switched to Safari first and then to Firefox. 

To put the 20-25% into context: A video conference consumes about the same CPU on that Macbook.

Question to Zendesk Agent users:

Which web browser do you use to achieve lowest CPU usage when working as Agent in the Zendesk Web GUI?

I see Firefox (currently v104) as lowest CPU usage with around 16% total machine CPU usage on a Macbook with 6 intel CPU cores and running macOS 12.x Monterey. Other browsers appear to use much more CPU on the Zendesk Agent Interface.

When hiding the Zendesk window completely behind other windows or when switching to a different tab within a multi-tab Firefox window the CPU usage drops to about 1%.
