I did not notice such a great speedup as in the reddit thread, but no slow-down either. PP may indeed be faster.

My recipe is not easily reproducible at this time so I’m refraining from posting. However, the B12X fork shows definite promise

Edit: Nevermind on speed! I passed in --enable-flashinfer-autotune and I’m now seeing bursts up to 60t/s!
