the last two rows are where we lose, and it’s not close - regex uses Teddy/SIMD for literals and short alternations, and we simply don’t have that yet. the case-insensitive row is the opposite story: regex falls back to an NFA when case-insensitivity with (?i) blows up the state space, dropping to 0.03 MiB/s. yes, that 16,833x number is real - this is exactly the NFA slowdown i described in the previous post. it’s not a contrived input, just case-insensitive matching on a dictionary. O(n * m) is technically “linear in n”, but when m blows up it stops feeling linear real fast.
