generally it wouldnt unless the user has mucked about witht he window size badly and no used something liek tcpip optimiser , basically you set the window size let says to 1024000000 instead of say 2048 (no i cant remmeber the windows size off the top of my head jsut a plain example being obviously different) then sendinga a packet not jsut tcp ping packet would be affected in time
