That's a good point. I wondered why the transfer was taking 26 minutes also. Since he said he tested with those other tools and got 6m/sec (I guess he meant 6 megabits per second which is OK, thought not great), the file transfer speed is probably due to a really slow server or maybe a slow client. We may be able to rule out the router and firewall since they were in the picture for the other tests too. However, they might be relevant since they were undoubtedly applying different rules when doing the file transfer versus the other tests. With a sniffer you can often tell where the bottleneck resides. Or maybe it will be obvious because he'll tell us that the server or client is a 286 sitting on dial-up home network. Just kidding. He should do some more tests and if he wants our help, give us more info. What is the server? What is its OS? Was it FTP he was using? What about the client? What is the config on the router and firewall? What else has he not told us about NAT, VPN, tunnels, etc.? What variables were different for the one test versus the other?
