wrk (used in the tests) [1] is a multithread/connection benchmark tool. <br>
You can simulate how many clients you want (basically you are just limited by ephemeral port tuple count ~65k .. but then again can work around it by assigning multiple IPs to the server/client).<br>

There is something different between simulating many clients with one real client and actually testing with many real different clients. I can't put my finger on what the difference is. But there must be a difference. Otherwise why is my application running into such performance limits as mentioned in this question on stackoverflow <a href="https://stackoverflow.com/questions/70584121/why-doesnt-my-epoll-based-program-improve-performance-by-increasing-the-number">https://stackoverflow.com/questions/70584121/why-doesnt-my-epoll-based-program-improve-performance-by-increasing-the-number</a> ?</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
