> The reason Stitch is slightly faster than Wasm3 on Mac, but slightly slower on Linux, is likely because Stitch has more variants per instruction compared to Wasm3, which puts pressure on the instruction cache. I suspect this gives Stitch the edge on the Apple M2 Pro, with its large instruction cache, but Wasm3 the edge on the Intel Xeon E312xx, with its smaller instruciton cache.
What means "more variants per instruction" here?
