As part of #148, we should decide on what benchmarking tool we want to use. Currently we're just having pytest print out test run times, but it was always intended for us to switch to using a more proper benchmarking framework at some point. asv is the primary (only?) benchmarking tool I'm aware of that's used in our space (e.g. NumPy, pandas, scikit-image, Xarray all use asv to monitor performance). Because of this I'm inclined to default to using asv unless there is a compelling reason not to do so.

Are folks aware of other benchmarking tools we should consider?
