TensorSharp Engine Boosts DeepSeek Inference by 2x with DSpark
fuzhongkai · reddit · 2026-08-03
Open-source inference engine TensorSharp now supports DSpark speculative decoding. The developer shared benchmark results for DeepSeek-V4-Flash-0731 running on 4x NVIDIA A40 GPUs.
The results show significant speedups with DSpark enabled:
- Short generation: 25.6 to 44.5 tokens/s (1.74x speedup, 87% acceptance rate)
- Long generation: 26.4 to 40.3 tokens/s (1.53x speedup, 66% acceptance rate)
- 10K-token document processing: 25.3 to 51.3 tokens/s (2.03x speedup, 85% acceptance rate)
TensorSharp is a local GGUF inference engine featuring CUDA, Vulkan, continuous batching, and speculative decoding.
