I've setup a ASV project and am in the process of teaching myself how that all works. I'm just playing with some simple arithmatic benchmarks for now but, of course, most of our interested will be in the i/o and dask arenas. 

I'm wondering if @mrocklin has seen ASV used with any dask projects. We'll just need to make sure we choose the appropriate timer when profiling dask functions.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,206632333

I have been doing a lot of benchmarking already wrt dask.distributed on my local cluster, focusing on performance with multi-terabyte datasets. At this scale, certain operations emerge as performance bottlenecks (e.g. index alignment of multi-file netcdf datasets, #1385).

I think this should probably be done in AWS or Google Cloud. That way we can establish a consistent test environment for benchmarking. I might be able to pay for that (especially if our proposal gets funded)!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,206632333

Especially as we start to get deep into integrating dask.distributed, having robust performance benchmarks will be very useful. One challenge is where to deploy the benchmarks.

I'm surprised there isn't something you can ask to just ""robustly time these tests"", so it can bolt on without writing new code.

I've done occasional benchmarks before to optimize bottlenecks (e.g., class constructors) but it's all been ad-hoc stuff with `%timeit` in IPython.

ASV seems like a pretty sane way to do this. pytest-benchmark can trigger test failures if performance goes below some set level but I suspect performance is too subjective and stochastic to be reliable.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,206632333
