Why such poor results with a simultaneous request on the route?

Question

Node.js

I did an experiment. I set a settimeout for res.send 10 seconds and opened 6-8 tabs one by one. As a result, the last tab loaded at least 25 seconds. Why not 10? Is it that, it turns out, several users at the same time on one route can put it down, cause such a delay in the response?

Answer 1

several tabs are not several users, but one.
