Faster because it isn't (currently) using compression (which rds uses by default) or faster period?

Either way, the idea of mixed Python/R pipelines with feather file intermediates input/outputs is pretty sweet. Learn in scikit, save to feather, plot in ggplot2... using Make to tie the pieces together?

It's usually faster than either compressed or uncompressed RDS - but if you have heavily duplicated data, compressed RDS can be faster than feather (depending on some tradeoff between compression speed and disk speed). Feather will probably gain compression support eventually.
