At my office we use a LAN (connected to internet through Comcast) and 30-50 people all accessed a web app (on Heroku) simultaneously. The server responded as if it had been hit by 50K people. Am I barking up the wrong tree, or would it make a difference if 50 people on an office network hit an app at the same time versus 50 people spread across the globe?
Apologies for such a vague question, but it only just occurred to me as a possibility.
Thanks in advance.
Having 50 people access your app simultaneously will have roughly the same effect, no matter where they come from. There is no more effort required to serve local requests than global requests (or vice versa). If your app has a performance problem, then consider yourself lucky that you’ve exposed it before turning on public access!
