We have customers updating over 100 elements on screen every second, but to get such rapid sub-second updates is not always realistic in a web browser.

Network requests can take 50-500ms (or more) even on local networks, depending on the networking hardware and configuration. Then the web browser needs to process the incoming data and update elements based on your own javascript or the Web HMI markup rules.

There are too many variables so any performance metrics are impossible to supply. We suggest experimentation within your own web application code and networking environment to determine your performance benchmarks.
