Rule of thumb on Sorting...supposedly

More of a click-bait post, counter to my normal musings.
You have been warned.

Sorting algos listed fastests (above others in
the same grouping [Log Scale] as proclaimed generizable assertion)
according to assembly enthusiast you-tuber (reference on PM request
if interested):
Small number of elements = Insertion sort (max 50 to 100 elements)
Mid size number of elements = STD-STL sort (up to max 1500 or so)
Large sizes = Radix sort (very large 2000+ and beyond)

Your thoughts appreciated. My own crappy code attempt
to follow.

Are you pondering what I'm pondering? It's time to take over the world ! - let's use ASSEMBLY...

Different way of sort, new kinda challenge , wonder what will be fastest with unicode Chinese numbers?,ascii is simple 0-9 all in right order
Chinese unicode number characters, is random order 1,2,3,4,5,6,7,8,9,10,100,1000,10000...
Is placed maybe complexity or number of lines among cjk kanji characters?

ArraySort() uses a radix sort. It is very fast, and beats all other algos when sorting small integers, e.g. up to 2^16 or so. For strings I use a stable MergeSort instead.

For all sorts 2000+ is not "very large" but rather "tiny". Sorting 44,000 strings takes typically 70ms, but for one Million strings you need a full second. Sorting small numbers of elements (<10,000) is always blazing fast. The real challenge starts above one Million.

Maybe you'll be interested in Skip-list algo for Large sizes lists.
