Confused by perft results: VICE in C vs VICE in JS

[syzygy]

while C is compiled without optimizations

It is pointless to compile C code with optimizations disabled and then compare speed.

[Richard Allbert]

The problem is - HOW ON EARTH your JS version is only 1 second slower with "tricky position" (as you called it in your videos)
compared to the C version???

Well, there is the fact that the C code is not optimised at all, so you may not be comparing the best case of each.

I'll take a look at the videos!

Regarding other engines, I'll need to dig out the code, it was a while ago.

I would greatly appreciate if you share it!
I'm your biggest fan.
Thanks to your videos I've learned to code and became a freelancer.
If you don't want me to expose it to public - no problem.
