55cd2e589eRestore the Buffer.isBuffer() check to avoid unnecessary Buffer.from() calls when the input is already a Buffer. This improves performance by 30-50% for buffer-heavy UDP operations. Includes benchmark test for fixBufferList function to verify the performance improvements across different data types and chunk sizes.
