I'm just trying to play around with my laptop by hosting a small WordPress blog on that. I wonder how many people it can serve at once.
About the network, I've tested on Speedtest.net and got this result: https://www.speedtest.net/result/8478472643
About the hardware, it runs on Windows 10 Pro 64bit, Intel Core i5-7200U, 8GB of RAM, and 1TB Samsung QVO SSD.
This depends on your WordPress setup and configuration - and what your users are going to do with it.
A simple and plain WordPress on a i5 Windows 10 (IIS/PHP7nts) may serve tens of thousands of users, but if they are searching the site, doing a lot of logins of use the comment function heavily, this may shrink to a few hundered parallel users.
Bandwith will most probably not the bottleneck in this case, nor will latency. I'd bet on CPU/RAM as the constraing factor.
