> Sorry for the delay. I don't really have a problem with enabling optimizations; if they improve runtime performance, we can pay the price in compile time. The question is how much PGO makes improves things for the average user if the optimization is tailored to the build system. I'd like to test a few things, including building on different CPUs to see how well the optimizations translate.

As a data point, I built this on my box (i7-9700). Running the sagemath testsuite with this (in the same box) takes ~5% less time to complete. As in 12:00 vs 12:30 for the normal test, and 23:17 vs 24:40 for the long test using 8 threads.
