[Pkg-openssl-devel] Build commands of official openssl package on Ubuntu 18.04

[Dat Le]

Hi,

I'm not sure if this is the right place to ask, I'm sorry if not. I just see this email as the maintainer contact of official openssl package on Ubuntu 18.04.

My issue:
I am investigate openssl to apply it to encrypt some large files. I want to be able to compile openssl from source (https://github.com/openssl/openssl), since I need to add some debug log and some time-measurement code to observe the performance.
I start to build compile with the original source at tag "OpenSSL_1_1_1" follow this instruction: https://www.howtoforge.com/tutorial/how-to-install-openssl-from-source-on-linux/

But when I run some encrypt demo with the new-build openssl, the time consumes to encrypt is somehow bigger than the one with the official openssl package installed by "apt install openssl".
I guess that the options of "./config" command are different between 2 openssl builds.

My expectation:
I hope to find the full build commands (with options for ./config, make) for the official openssl on Ubuntu 18.04, to make sure my self-complied version doesn't change too much from the official.
Currently, I can only gleam limited information from the "openssl version -a" command
