Research direction

Start by locating the ByteStream implementation and the encoder call sites that append one byte at a time. Trace the encoding path and establish a performance baseline before choosing a batching approach; done means the output remains correct and the reported single-byte append overhead is reduced.

Written by the indexing model from the issue text.

Description

During encoding, the encoder frequently writes data one byte at a time. This step introduces considerable unnecessary overhead, and the computation pipeline can be streamlined to improve performance.
