Vasanth performed his benchmarking tests again and found no change in the results, so the remarks in our PDF are still current and valid. If there aren't any concerns with how we're checking performance without DMA, then perhaps we should double-check this on an ARM platform and then proceed? Best, Rhett Aultman
