Compared two computer, one with windows 2000 prO and the other, IMAC G3. Upload a file (pdf) size 5mb to a secured server(https) with G3 took 3 seconds but with Win 2000 took 2 min 12 sec. What a difference!! using the same high speed connection. Could be related to the net stack (TCP/IP) of windows 2000 and what is the solution? Need help.
