In the case of miniFE, the performance has pulled back in GCC 9 and remained slower on GCC 10.

FFTW meanwhile saw better performance since GCC 9 and is remaining that way so far with GCC 10.

For many workloads tested on this Haswell Extreme Edition system, the performance difference is minimal from GCC 5 to GCC 10.

HMMer was one of the cases that's sadly been sliding in the wrong direction.

Google's libgav1 AV1 encoder meanwhile is seeing a new drop off the current GCC 10 compiler code.
