As a spammer I wouldn't care much about this, they run thousands of requests in parallel and don't care if they take 1 second or 10 seconds to finish. After all, their machines run all day long. Much of the more professional spammers are running on hacked botnet machines anyways so they don't really care about maxing the CPUs. Compute is cheap and the only loser here is the end user with a low end device.
