Yeah, I mean, but cache is inherently somewhat unreliable, in that even at best its availability varies from processor to processor even on the same architecture in terms of amount and sometimes speed. It also is hard to figure cache misses, and sometimes hard to track down why your functions aren't being held in the cache lines - maybe your locality of reference stinks or something.

Look, I get your point about not bothering with this stuff in general. In general I wouldn't.

But this is

1. Critical code in terms of performance. I expect to be able to find tens of thousands of matches through some text in milliseconds. For code like that it is worth doing the legwork to find out how to make it faster. Even 20% is worth it.

2. Generated code, so the priorities aren't strictly about readability or maintainability, but even if they were, the change I proposed doesn't really impact readability. Furthermore, being that it's generated by a programmatic process, it pays even more to make that process produce the fastest code reasonable, given #1 (note I didn't say possible, I said reasonable. A 20% gain as a general rule of thumb is easily reasonable for generated code, even if readability is impacted somewhat). If .NET 8 changes the landscape significantly I'll update my code to reflect that.

3. I'm not doing anything Microsoft hasn't done in terms of optimizing their generated code to produce optimal output. I guarantee you they smoke this thing with benchmarks before every ship, and bits get twiddled. My goal was to beat them at this task, for reasons. So I have to play at the same level they are.
