Ran Laguna S 2.1 *theoretical* (not measured) upper bound calculations for the DGX spark

poolside/Laguna-S-2.1-NVFP4 - max ~25 tok/s single session. if you are willing to go down to 12 tok/s, you can have 4 sessions in parallel

vcruz305/Laguna-S-2.1-GGUF (IQ1_S) - max ~74 tok/s single session. theoretical 5x20 tok/s = 100 tok/s aggregate upper bound

Calculated assuming no speculative decoding, so might increase well over these numbers

See my local frontier app and my previous posts for more info on the methodology
