There are various tools for that. The principle is that you should start some dummy servers on other instances (or at least fast static servers such as nginx), and run injection tools on other instances. Such tools might be httperf, ab, inject or any such thing. You will then configure your haproxy to forward to the dummy servers and will send your injectors' requests to haproxy. The tools will tell you the data rate, connection rate, etc... You're encouraged to enable the stats page on haproxy so that you can check rates and errors in live. In general, for 5k CPS, you need a bit of system tuning, because most Linux distros come with a conntrack setting which is only valid for a desktop usage but not for a server usage, so the traffic will suddenly stop after a few seconds. Or better, simply disable the module. Also, it is important that you have at least two machines for the servers and at least two for the clients, because in such environments, you have no visibility on anything, and it's quite common that some VMs are struggling or that some network paths are saturated. If you see that two servers behave differently, at least it's easier to spot where the problem is. Regards, Willy
