What with the number of Apps and Scripts workers are running these days, we have to be careful not to overwhelm the mTurk system. Doing so can result in warnings, Page Request Errors (PREs), or even a ban. OTTO's professional advice is to keep your Total Page Request Rate at or above 0.8 seconds. If you drop below this rate, please be advised that you do so at your own risk.

Enter below your current speed settings for any tools you are using. If you are not using a tool, enter 0 for that line. The goal is to achieve a combination that results in an effective page request rate greater than 0.8 seconds.
