Research direction

Start with the linked node-jwt-benchmark reproduction and compare jsonwebtoken 8.5.1 with 9.0.2 under Node v20.12.2, focusing on the reported HS256 encoding and decoding results. Done means the source of the regression is identified and the benchmark shows verified improvement without breaking the reported algorithms.

Description

Description

The performance of jsonwebtoken 9.0.2 is 50 times slower than 8.5.1, mainly in the HS256 algorithm.
The encoding speed has slowed down by 53 times, and the decoding speed by 34 times.
