Re: Proposal for enabling auto-vectorization for checksum calculations

Hello! I'm still trying to figure out those CI failures, I just wanted
to update things.

From my testing, with this patch repeatedly disabling/enabling
checksums is about 12.4% on an approximately 15 GB database.

By the way, I'd love it if anyone could help me figure out how to
replicate a CI failure in the Cirrus CI.
I haven't been able to figure out how to test CI runs locally, does
anyone know a good method to do that?
