⚡ Bolt: [performance improvement] Optimize yEnc decoding - #174
Conversation
💡 What: Replaced byte-by-byte python loop with C-backed bytes.find() and bytes.translate(). 🎯 Why: yEnc decoding was heavily CPU bound due to manual byte iteration. 📊 Impact: ~15x faster decoding for article bodies. 🔬 Measurement: Micro-benchmarking shows time drops from 2.22s to 0.14s for 10k lines.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |
