The longer between your requests, the better. If you generate a load greater than what a human would do, this might become problematic. A human wouldn't poke a website forever every 10-15 seconds. The 10-15 seconds is more for web crawlers. Eventually, a crawler will run out of pages to crawl on a website, so it will stop sending requests to it. Personally, I would stick to the 3 minutes delay. But it depends on what type of website you're scraping :)
