[Bug 2009544] Re: OpenSSL 3 performance regression

[Antoine]

Not easilly reproducible for others but one of our dotnet application uses openSSL to compute some cryptographic hash and here's the ratio of performances:
Ubuntu 20.04 + openSSL 1.1 : 100 % 
Ubuntu 22.04 + openSSL 3.0 : 5.1%
Ubuntu 22.04 + openSSL 3.2 (custom compilation not at all realistic) : 50%
Those were run with latest available version availalble the 22 of march 2024 in official repo.
Those performance number are quite concerning I hope future release of openSSL 3.0 will address those performance issue which makes Ubuntu 22.04 (potentialy 24.04 as well) not usable for any openSSL heavy reliant workload.

Status in openssl package in Ubuntu:
  Confirmed

Bug description:
  Hello, it sounds like there's some significant performance regressions
  in OpenSSL 3:

  https://github.com/openssl/openssl/issues/20286#issuecomment-1438826816

  Some we might be able to address with:
  https://github.com/openssl/openssl/pull/18151

  Some of the performance differences may be subject to ongoing work.

  Thanks
