Feel free to make a PR to use radix sort, but first this should be upstreamed to SortingAlgorithms to avoid adding too many dependencies to DataFrames. Does fsort implement things that JuliaCollections/SortingAlgorithms.jl#33 doesn't cover?
In DataConvenience.jl I tried out a radixsort based sorting approach and I found there is still some performance gain to be had in the sorting
