Обсуждение: OpenSSL v3 performance regressions
Hello, I read this article from Haproxy, they noticed OpenSSL v3 has huge performance regressions : https://github.com/haproxy/wiki/wiki/SSL-Libraries-Support-Status#openssl This is a known issue : https://github.com/openssl/openssl/issues/17627#issuecomment-1060123659 Unfortunately, v3 is shipped with many distributions (Debian, Redhat, Rockylinux...) : https://pkgs.org/search/?q=openssl I am afraid of users will face performance issues once they update their distro. Does someone already encounter problems? Should Postgres support alternative SSL libraries has HAProxy? Regards, -- Adrien NAYRAT

PostgreSQL can be built with LibreSSL instead of OpenSSL, which may or may not be a better option performance wise for a particular application. Benchmarking your workload is key to understanding performance, a lot of the regressions pointed to in that blogpost wont affect postgres. -- Daniel Gustafsson
