Cool that there are some specialty tools in this space and will use if I hit that performance challenge.

Minor nit, I found the performance table (https://github.com/eBay/tsv-utils/blob/master/docs/Performan...) confusing at first and second glance. Alternating colors indicate.. different OSes? That doesn't seem to be the important message to convey as you are trying to show the speed of your tool and not the OS. Recommend to use the coloration to provide differentiation between tools instead of OS.
