I guess the benchmarks are run on nightlies from 3.15 dev branch? It doesn't say on the website.

I did some tests with 3.15-dev on my own reference benchmark a few days ago and noticed that the JIT is finally making a positive impact.

As it looks now, 3.14->3.15 will be the biggest release-to-release Improvement since 3.10->3.11. At least for streaming text processing with significant amounts of pure-python logic.
