FWIW, I wasn't - I was assuming that 40:1 is fine if what you intend to support is browsing only. > If you have one person trying to watch streaming video while another > person is uploading pictures to facebook, you can run into trouble at > much more even ratios. Restated, you run into trouble because you sold a service you didn't provision for ;-) (or, more to the point, you took a gamble that you could sell a useful service with a particular assumption about traffic ratios, and that assumption no longer holds) Again, IMO TCP isn't to be tampered with merely to support a business model, and that's all I see so far.
