Summary
User benchmarks Qwen3.8 Flash-Next at 34.8 tok/s decode on two Tesla P40 24GB cards with a layer split, and 19.6 tok/s on a single P40.
Setup is Strata v0.1.39 with IQ2_XS weights at 32,768 context, experimental CUDA 12 engine built locally; the two-card run splits layers across both GPUs (K=24, all 24576 profiled expert pairs resident).
Prompt reading was 353 / 501 tok/s at 4K / 16K on both cards and 348 / 388 tok/s on one; figures are medians of 3 runs per cell, with the first run of each configuration slower due to expert-cache warm-up. A 69-task correctness suite ran twice, and two greedy runs of identical prompts gave 49 of 69 identical outputs.
