Dev Slams SGLang/vLLM Stacks as Buggy: Massive Low-Level Perf Work Remains
tekbog · x · 2026-09-24
A viral post by zekramu complains that current LLM inference stacks — SGLang, vLLM and others — are buggy and under-optimized, with low-level kernels and MLX still leaving huge headroom for performance engineering.
Quoting it, tekbog adds perspective from systems engineering: popular programming languages have long been held together with duct tape, and good engineers build reliability by layering guardrails on top of unstable foundations — that's just the reality of the computer business.
