Improve splitPart function

Open gortiz opened this issue 3 months ago • 2 comments

The split part function (link) is allocation-heavy.

It first calculates all splits and then only returns the one indexed as requested by its argument. That is very allocation expensive when the index is very small and the separator is repeated several times.
