handshake fails with thread counts 500 on some platforms

[quarckster]

I observed failing of handshake benchmark on debian-x86, macos-x86_64 and macos-m1 platforms when thread count argument is set to 500. It seems it starts failing after some thread count threshold. I built perftools against OpenSSL_1_1_1-stable. I also tested it against master branch of openssl and the issue is still observed on debian-x86. MacOS is not affected on openssl master.

debian-x86

That looks like an answer

I think we should close it as won't fix or not-a-bug. 500 threads can eat significant amount of memory system must reserve. 500 threads creats more stress to OS (especially 32-bit OS) itself than to OpenSSL library.

I think if you want to use 500 threads you need to make sure your OS (and HW) is able to handle it.

I'm closing the issue. If anyone disagrees, then feel free to re-open.
