 Could there be induced bottlenecks as a result of the lan perimeter
 parameters ?
 What kind of connection is being realized to the Intranet.
 Check port status on network hub, watch for possible errors over there.

 If the same file size is being transferred from the SQUID machine
 to a SQUID client, without SQUID, I mean , just ftp a file
 from the machine to the Intranet, are then the same bottlenecks
observed ?
