For some reason, I can't display your message. I got to display it now. I don't have a good comparison performance format for ML-KEM. But here is the raw performance number for MLDSA.</div>

I just noticed that we do have support for MLKEM and MLDSA in our<br>
./bench-slope . We should change that to make it easier torun<br>
benchmarks.<br>
<br>
I was actually looking only for a rough figure on how much performance<br>
you gain with your patches.<br>
