WebFor rate limiting, you definitely do not want to use time.clock (), which measures elapsed CPU time. CPU time can run much faster or much slower than "actual" time. You want to use time.time () instead, which measures wall time ("actual" time). – John Wiseman Dec 21, 2015 at 23:42 3 WebThe fixed window algorithm is a method used by rate limiting tools to track and throttle requests by dividing time into fixed intervals, or windows. Requests are counted within each window and if the number of requests exceeds a predetermined limit, subsequent requests are throttled until the next window.
