I looked into this a little bit; the main thing that pops out to me is that the dev42 version spends a lot more time generating many more `CatLinearOperator` objects...

Hi @jduerholt, what exactly are the use cases for the functionality you built on your end? @sdaulton has used `optimize_with_nsgaii` to do multi-objective optimization across different acquisition function as sort...

That sounds great. Do you have a high-level design in mind? Could make sense to align on that before starting a PR.

Thanks for raising this, this is a great catch. Since this call happens in gpytorch we'll have to make a change there and ensure that it is compatible with all...
