so i have a server on the our edge switch and trying to download a 100mb file from the core and it takes about 3min 30 seconds through a pix v 6.2. when i put this file on the dmz it takes about 20 seconds. now when i ftp im using port 2021 and downloading from server to UNC path of mapped drive. when i do this locally, download time is about 1min 30 seconds. any ideas what could be bottle necking?
