AWS-Lc looks very promising replacement for OpenSSL these days.

I looked into this and was tempted as there is less read locking and better RNG performance but they stripped the SSL_get1_curves() API which I depend on for bot detection plus I would have to recompile nginx and all its modules everywhere so in the end it was not tempting enough for me. Perhaps I am just lazier in my older age.

		We ran a number of tests, including sending a percentage of real traffic to endpoints running AWS-LC and Wolfssl. Technically yes, OpenSSL 3.X is slow, measurably so, but not enough that we wanted to deal with it. That's for our use case, I can easily imagine there being others, where maybe you have different hardware or way more traffic, where it would be worth while. For basic TLS termination in haproxy, it wasn't really worth it to us.

		Nothing wrong with being frugal with your time!
