Is a client robot an OS thread?

[Kevin Xie1]

Thanks for your quick response, Dmitry.

However, I don't understand how a single thread can simulate multiple concurrent "users" submitting request to web servers. Is it that the single thread iterates all open connections one by one (submitting a request or processing response one at a time)? This can be easily bound by CPU since just 1 core is used at a time, or by slow connections ..., do I miss something here, or my understanding is fundamentally wrong?

Appreciated for any light shed!

Kevin

Polygraph client and server processes are single-threaded.  All Robot
and Server agents are running in a single thread.
