People addicted to speed. ;^) I might be being argumentative for it's own sake (sorry), but doesn't this make Chrome less sensitive to DNS performance rather than more sensitive? With a browser that doesn't pre-cache DNS lookups, the user is aware of DNS latency every time they click a link and with every resource that the browser loads from a different domain. Conversely, with caching, in most cases pre-caching every link on a page will take longer than it takes the user to find a link and click on it even if the DNS cache is extremely slow. Now I'd agree that faster DNS servers makes a noticeable difference when browsing since many websites load content from a dozen or more hostname, but I'd argue that Chrome's precaching makes it less sensitive to slow DNS queries. -- Dave Warren, CEO Hire A Hit Consulting Services http://ca.linkedin.com/in/davejwarren
