Self-hosted Claude Code speedup achieved via caching and header stripping

By PulseAugur Editorial · [1 sources] ·

A developer detailed how they significantly sped up their self-hosted Claude Code setup by addressing two key performance bottlenecks. The primary issue was a rotating billing header injected by Claude Code, which caused cache misses on the vLLM-MLX backend. Additionally, vLLM-MLX's SimpleEngine lacked persistent KV state for system prefixes, requiring a custom patch for caching. Implementing these changes reduced turn times from over 100 seconds to 7-8 seconds, a 13-15x improvement. AI
