These instructions explain how to build OpenSSL 1.1 and the traditional libcrypt (specifically libcrypt.so.1 from older versions of glibc). This enables us to run versions of OpenShift's HAProxy that were linked against OpenSSL 1.1 and the older libcrypt on RHEL/Fedora systems where the runtime platform now only provides OpenSSL 3 and the newer libxcrypt. We need the older libcrypt because the OpenShift HAProxy build depends on it, and the newer libxcrypt is not fully backward compatible with the original libcrypt.

Build OpenSSL 1.1.1 on Fedora 40 (possibly RHEL?)

NE-1690 - Analyse Memory Impact of Pre-Allocated Server Slots for Different Numbers of Routes

HAProxy version 2.8.5-aaba8d0 2023/12/07 - https://haproxy.org/

Column headers:

• ST=<0|1> (server-template disabled=0, enabled=1)
• Tn (Number of Threads)
• RSS (Memory usage in MB)

I have been collecting memory usage data for HAProxy's server-template feature, where the range is 0..N - this is the ST=1 column.
