In case someone is interested, here are some benchmark results comparing GraalPy and others with JDK8 using the Are-we-fast-yet benchmark suite: https://stefan-marr.de/downloads/tmp/awfy-bun.html
And here is a table representation of all benchmarks and the geomean and median overall results: http://software.rochus-keller.ch/awfy-bun-summary.ods
The implementation of the same benchmark suite runs around factor 2.4 (geomean) faster on JDK8 than on GraalPython EE 22.3 Hotspot, or 41 times faster than CPython 3.11. GraalPython is thus about 17 times faster than CPython, and about two times faster than PyPy. The Graal Enterprise Edition (EE) seem to be factor 1.31 faster than the Community Edition (CE).
Your mileage may very much vary, much like pypy this is very inconsistent and highly dependent on your workload (as well as your dependencies).
My limited experience was that on re-heavy workload pypy is several times slower than cpython (~3x compared to 3.10) and graal is even worse (~6x compared to 3.11).
