Benchmark测试

============================================================
  Qwen3.6-27B Heretic W4G128  —  Benchmark
  3 run  ×  1024 output tokens
============================================================
Run 1/3... ✓  TTFT=281ms  TPS=43.5  (522 token)
Run 2/3... ✓  TTFT=69ms  TPS=43.4  (522 token)
Run 3/3... ✓  TTFT=69ms  TPS=43.4  (522 token)

 Run   TTFT (ms)   TPOT (ms)       TPS    Token   Total (s)

 AVG      139.48       23.01     43.45        ─           ─

平均43.5t/s，比之前我在log看到的86t/s低很多。原因可能是benchmark.py只生成了522token，没到1023，而且这是纯文字短回答，prefix cache没热身。注意TTFT第一次281ms，第二次69ms，prefix cache命中后快了4倍～TPOT 23.01ms，每个token约23ms。

不知道KV还能不能再往上冲，毕竟是多模态，不审查内容跟不审查图片识别都已经测试没问题了～请大神帮忙看看KV跟TPS还有什么可以调整的空间～感谢感谢～第一个帖子搞得不好还请多包涵～

对了，模型二我就没有贴了，因为效能不如我自制的模型，我是看了几个老外的帖子说很厉害85-110TPS，结果试了之后才34，我这个也有上到85的时候，平均比Lorbus多～但我又看到另外一个说用NVFP4+MTP也很厉害，可能晚上我也来折腾一下，试试自制NVFP4 + MTP跑一下～以上汇报～
