Hello!

There is a task to launch as many sessions as possible in a short time and for a certain time - 5-10 minutes, log in and perform certain actions (press buttons, fill out forms, collect information).

Before that, I used puppeteer (including headless), but it turned out to asynchronously launch only about 10 chrome windows without problems, then the program started to lag. I tried to split it into processes and threads, the result is not much better and instead of the program, the computer began to lag.

Ideally run 30-200 sessions, are there any solutions for a similar task? Not necessarily on nodejs.

Answer 1

There is apache jmeter
big question what you need for interactive.
If you know Java, then you can generally write your own module

Answer 2

Observations running 2 million headless sessions
