Comment 15 for bug 1970521

Looked at potential performance regressions of removing AVX instructions.
(Updated the SRU template sections accordingly.)

The boinc packages do not provide high-performance code, it's the boinc
_applications_ written to be run by the client and linked against the
library for API access that have the high-performance code, IIUIC.

The API documentation/headers do not seem to provide any high-performance
functions (e.g., the crypto part are wrapper for openssl), the only code
it seems to implement is MD5.

Considering this change has been introduced in Debian ~2 years ago
(Feb-Jun 2022) and in Ubuntu Kinetic (22.10) and is still in place,
there indeed does not seem to be a performance regression (or other
issues related to it).
