Only use dynamic delays for the crawler. Even though the max wait was 1 second the number of waits could severely impact crawler speed. Instead of relying on a global metric, we use the stateless local delays to keep the crawler running at a speed more adjusted to current conditions. The only case we keep it is before bitrot checks when enabled.
