- Read chunk size lines and trailers in 64-byte blocks instead of 1 byte
at a time, pushing back excess data to the unreader buffer
- Reuse BytesIO buffers with truncate/seek instead of creating new
objects to reduce GC pressure in AsyncUnreader
- Use bytearray.find() directly instead of converting to bytes first
in header parsing loop
- Use index-based iteration for header parsing instead of list.pop(0)
which is O(n) per pop vs O(1) for index access
Add tests for the optimized parsing code paths.
