Muse Glimmer 30B Speculative Sampling Slower Than Vanilla Due to Low Acceptance Rate
No_Algae1753 · reddit · 2026-08-11
A developer running the Muse Glimmer 30B model via llama.cpp on a MacBook found that enabling DFlash speculative sampling resulted in slower generation speeds than the vanilla mode.
Issue Analysis:
- Tests showed a very low acceptance rate (around 10% to 30%) for the DFlash drafter model.
- The overhead of running the drafter outweighed the time saved, degrading overall inference performance.
