That's pretty cool, C# performance chasing can be fun or maddening. Thompson NFA was obviously a good choice based on the speedup. But after reading this article I'm wondering if it was the best choice for all-out performance: > The rust-regex program is quite a bit faster, but primarily because it uses a different technique for this particular regex (a lazy DFA). [edit] Point being, different techniques work better for different use cases. To deal with this aspect of performance chasing I wonder, since multi-core is more prevalent now (than in 1968), if it would be the ultimate in performance to fire off a few different techniques simultaneously on different cores and let the first one take it. That would bypass the need for analysis before choosing a technique.
