As the maintainer of ripgrep, I pay attention to these sort of things. I will say that I noticed a similar performance problem in my tests as well, but further investigation revealed that Window's antimalware process was severely throttling file reads. Once I disabled that, performance on Windows is nowhere near an order of magnitude worse than Linux.
