Unfortunately this will be rather impossible with the MTU currently set to 1536 the 2048 byte packets must be coming from another source (router to router connections?). So the number of 2048 packet will stay the same, but the 1536 ones will triple (adding ~20% more packets in this scenario). The big win (from the users perspective) is that web pages update quicker. Instead of sitting there waiting for a large packet to come in before a page is partially updated the user could have 2/3 of the data already onto the page. While it might not be "the right thing to do" from the perspective of helping the "internet" function the perceived speed by the end user is higher and that is part of the battle we are all fighting (witness the coming deployment of more localized caches). bye, ken emery
