A solution is great over the LAN for the most part - it also greatly depends on how the solution is created.
But it seems to me that once a solution goes outside the LAN and gets accessed through the WAN, thats when we see a dramatic change in performance. Lately the way we have been dealing with this is to architect solutions very deliberately to work better over a WAN. More work and more attention to detail but the results have been great. Wish we did to have to do that and wish there a similar performance for both of these.
