If one part of your pipeline is very expensive (perhaps reading the original data from disk?) then the process of saving can be very slow.

I would suggest doing some profiling, e.g., as shown in this example: http://docs.dask.org/en/latest/diagnostics-local.html#example

Once we know what the slow part is, that will hopefully make opportunities for improvement more obvious.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,435535284
