A C++ program that spawns as many threads as it can to open TLS 1.2 connections to a given server and send random data.

Needed this to test scalability of one of our services.

    Something like that is fun to write yourself. Maybe use library if you're not familiar with sockets yet

    Also, why c++? The network will limit speed anyway. I would use aiohttp python lib

    can be written in majority languages' core network stack
    Do limit the threads to double digits tho, I remember I did something similar with ICMP ping ages ago during my internship n for some N+ threads, Ubuntu did a Kernel Panic and the network driver/device crashed, only way to fix was a reboot (service restart didn't help either)

    not a heavy-Linux guy so maybe theres better ways to circumvent it (if it hasn't been fixed already), but if you do spawn unlimited threads, try to keep 50/double digit active ones, (thradpool works)

    @azuredivay This runs easily with 2500 threads on a VM with 4 cores. Anything north of 2500 and madness will ensue.

    @retoor I don't do Python because I care about the rain forests. How much Carbon dioxide will running Phyton code generate?
