I don't use benchmarks but just for the heck of it I tried Scimark4:

https://math.nist.gov/scimark2/whatsnew.html

The results using highly optimized compiler options on my Gentoo
system and Xeon workstation:

FFT Mflops: 2338.10 (N=1024)
SOR Mflops: 2062.17 (100 x 100)
MonteCarlo: Mflops: 943.78
Sparse matmult Mflops: 2550.52 (N=1000, nz=5000)
LU Mflops: 8320.08 (M=100, N=100)

************************************
Composite Score: 3242.93
************************************

Not bad! It ranks #2 of all results posted on the "Results" page.

Next, the software was built from generic, lowest-common-denominator compiler options
just like the average Linux distro. The results:

FFT Mflops: 1868.69 (N=1024)
SOR Mflops: 1520.70 (100 x 100)
MonteCarlo: Mflops: 762.05
Sparse matmult Mflops: 2771.88 (N=1000, nz=5000)
LU Mflops: 4883.40 (M=100, N=100)

************************************
Composite Score: 2361.34
************************************

Holy tabasco sauce! It's almost 1000 Mflops lower!

The conclusion is undeniable. All the Gentoo bashers haven't
got a leg to stand on.

Unless one builds his own optimized Linux, one is getting seriously
shortchanged.

Systemd free. D.E. free.

Always and forever.
