For medium sized stiff system biology ODE models I have recently done two benchmarks that suggest that CVODE_BDF outperform the Julia solvers (in particular the multi-step bdf solvers). Below is an with 25 ODEs and 39 parameters. The model is imported with SBMLImporter.jl and I used PEtab.jl to set…

CVODE_BDF outperforms Julia solvers for stiff system biology model?

I can make a PR with the stiff models in the PEtab benchmark collection, to see if there is any trend.
