@timfel What do you think?

It mostly worked:

5 benchmarks failed:- dask (Benchmark died)- gc_collect (Benchmark died)- networkx (Benchmark died)- networkx_connected_components (Benchmark died)- networkx_k_core (Benchmark died)

It wasextremely slow:

I cancelled it after an hour.

Is it premature? Does it require much more powerful runner?

@maurycy we run the pyperformance benchmarks internally, but they require a powerful runner and lots more warmup than PyPy or CPython per benchmark. One hour is not nearly enough, we give it 18 cores and 64G of RAM and it runs in about 2.5 hours

As for the benchmarks, the networkx benchmarks should work, that's a bug on our side. But dask and gc_collect as are won't, the GC benchmarks in general just don't make much sense on GraalPy, since we have a completely different GC, so neither the benchmark nor any assertions make sense for us. The dask one doesn't work because we don't support thedis module, we have no current plans for this. So those would have to be excluded for GraalPy

This also increases the CI runs from around13 minutes to over2.5 hours.

That was just tests, though:

• https://github.com/python/pyperformance/blob/main/.github/workflows/main.yml#L79

Other tests finished in ~10 minutes

FYI: The whole benchmark runs in ~1h on cpython on i9-12900K, 128G DDR4

@maurycy if it's anything like in our internal setup, running the pip subprocesses to install dependencies is easily the worst part of the runtime. Thesecreating venv for benchmark steps are easily 20x slower than on CPython, and when 2s turn into 40s times ~90 benchmarks this fills the time quickly.
