[SciPy-User] griddata() performance

I'm wondering which performance I can expect from griddata. I will need
to interpolate from 4d unstructured data, with dimensions at least
5x17x38x52, and I need to get the 1d-values of ~ 15k points. So far, the
routine is running for > 30 minutes, and I'm wondering if this is to be
expected. My machine is a AMD Opteron(tm) Processor 8439 SE 2.8GHz CPU.
I guess there's no easy way to parallelize this?
Cheers, Andreas.
