## And against it

- "Performance degrades significantly above ~5,000 messages/sec without complex multi-worker tuning." (Kimi K2, Telemetry pipelines)
- "standard Fluentd runs on CRuby... it hits performance limits faster and uses far more resources" (Gemini 3.5 Flash, Telemetry pipelines)
- "Heavier and Ruby-based; slower than modern alternatives" (DeepSeek V4 Flash, Telemetry pipelines)
- "Lightweight log collection (not full pipeline)" (DeepSeek V4 Flash, Telemetry pipelines)
