Staggering Difference in Network Performance??

[Guest Bryan L]

I just tried to transfer a 500MB file from a server to my workstation.

Since I was already TS'd into my server I mapped a drive on the server to my

workstation (since I do this sort of thing fairly often) and started the

copy operation to "push" the file down to my worksation. Performance seemed

very slow to me -- after chugging away for a couple of minutes, the transfer

was still only 1/2 done -- so I decided to try "pulling" the file to my

workstation rather than pushing it from the server. The whole transfer took

less than 10 seconds.

 

Why should there be such a performance difference in transfer speed? Would

the drive mapping have anything to do with it? I used the \\server\share

path to pull it from the server to my workstation and not a drive mapping.

Both the server and workstation are very new so it's definitely not an

underpowered server.

 

HUGE difference in speed. Thoughts?

NIC drivers not up to date on one side? Network throttling on the

upstream via router / switch? In my own experience, "down" always

seems to transfer faster than "up" does. Is this a SP2 Windows Server

2003?

I have a user whose pc does just that.. tried an old card I had handy,

and just popped it into his XP workstation. whammo, problem solved...

 

also as the other poster said, check the drivers too...
