Description
For example, there's an old branch to use SSE 4.2 string instructions in tokenization, which realized a speedup of about 10% and could probably be pushed much further.

Research direction
Compare the old sse branch with the current tokenizer implementation and identify which tokenization paths it optimized. Establish a benchmark for the current parser, then evaluate whether further tokenizer microoptimizations produce a measurable speedup. Done means a clearly justified optimization with benchmark results.
