Performance Tips Reference Undocumented and Unsupported Features

[araray]

📚 Documentation Bug

Summary

The Performance Tips section lists options and strategies that are either not implemented or misleading:

---

❌ Issues Identified

• --chunk-size 64 is valid, but its impact on performance isn't documented or benchmarked.
• MmapBytes feature is mentioned but doesn't exist in code or flags (despite memmap2 being a dependency).
• Suggestion to “chain operations to minimize I/O” is invalid as chaining is not currently supported (see [Chaining Issue](https://github.com/araray/binfiddle/issues/XX)).

---

✅ Suggested Fixes

• Clarify that chunk size can affect display/output granularity, not I/O throughput (unless benchmarked).
• Either implement or remove reference to MmapBytes.
• Update chaining suggestion once --chain feature is available or remove it in the meantime.
