You Don’t Know Jack about Network Performance

Abstract

Why does an application that works just fine over a LAN come to a grinding halt across the wide-area network? You may have experienced this firsthand when trying to open a document from a remote file share or remotely logging in over a VPN to an application running in headquarters. Why is it that an application that works fine in your office can become virtually useless over the WAN? If you think it’s simply because there’s not enough bandwidth in the WAN, then you don’t know jack about network performance.
