How do you do Load Testing and Capacity Planning for Web Sites
That's a simple question. I am curious to how many people can access the web server at once on Linux?
My client said he expects hundreds of people to access the different videos at once but I am not sure if it's possible to do that on non-streaming media server. Has anyone done that?
That sort of thing is quite possible, it just depends on how the web server itself (there are several possible web-server packages for Linux) is configured. Thousands are easily within possibilities. For video you're much more likely to run into bandwidth constraints before you run into concurrent user constraints, though.
