I had to perform sites analysis for a customer a few months ago. Many web pages nowadays have between 100 and 200 objects to fetch, spread over up to 25-30 host names. If you take even only 100ms for each of them, you're at 3 additional seconds to display the page. Granted those requests are not WS and only HTTP, but as I said, SRV for WS won't work before it works with HTTP, at least due to proxies. But those 3 extra seconds will always be considered a good reason not to make SRV mandatory for HTTP. The web is degrading very quickly due to poor practices, and we should be careful not to suggest to make it even worse. Regards, Willy
