<h3>Hints</h3>
<ul>
<li><h4>Crawl Speed Limitation</h4> No more that two pages are loaded from the same host in one second (not more that 120 document per minute) to limit the load on the target server.</li>
<li><h4>Crawl Speed Limitation</h4> No more that four pages are loaded from the same host in one second (not more that 120 document per minute) to limit the load on the target server.</li>
<li><h4>Target Balancer</h4> A second crawl for a different host increases the throughput to a maximum of 240 documents per minute since the crawler balances the load over all hosts.</li>
<li><h4>High Speed Crawling</h4> A 'shallow crawl' which is not limited to a single host (or site)
can extend the pages per minute (ppm) rate to unlimited documents per minute when the number of target hosts is high.
