Why were pandas merges in python faster than data.table merges in R in 2012?
...n global string hash table. Some benchmark results are already reported by test.data.table() but that code isn't hooked up yet to replace the levels to levels match.
Are pandas merges faster than data.table for regular integer columns? That should be a way to isolate the algorithm itself vs factor...
