Re: Network Bottleneck

Well my math shows that about 4mb/sec, about normal for a 10mb connection.

Are all 8 workstations exhibiting the similar transfer rates?

What is the speed and duplex the NIC is connected at when set to auto?

What does the switch show for the port speeds for both the Server port and
the WS port (these should match).

Are there any entries in the event logs related to the nic on the
workstation or the servers?

What is the NIC type and did you use the Microsoft Driver or a vendor
driver?

What is the disk subsystem on the clients? IDE? what Drives, vendor and
speeds (7200?)?

What are trying to do, compare the performance of a server to that of a
workstation?

No KJ all we want is a reasonable file transfer speed to workstation. Just
to transfer a 15mb file takes 40 seconds, couldn't figure out where the
bottle neck is? Any suggestion?

Very interesting
I logged in to the server then opened my computer, and copied a file
from
\\ws2\c$\15mbfile

When I copy from ws2 to server it copies within few seconds But
When I copy from server to ws2 folder it takes 40-50 seconds.

Server has 2 nic, external is 10\100mb nic and lan is 1gig nic. the
switch
is dlink 10/100 fast ethernet switch.
On WS2 I tried to change auto, tried 10mb half, 10mb full, 100mb half,
100mb
full, and not much improvement. Any more suggestions please.

try setting the NIC speed on your cards from autosense to a fixed
speed
(you
might have to try various settings -- 100full duplex, 100 half, 10
full,
etc). or vice versa:

you may also need to research disabling smb signing, oplocks and or
autodisconnect:

We have SBS03 server with 2 nic, 1.5mb/256kb broad band, 8 pcs on
LAN
connected to Dlink fast ethernet switch.
The client computer are good, dual core pentium 4 with 512mb ram.
Internet
is pretty good as well. BUT when it comes to access Network
resources
its
DAMN SLOW. Don't know what is causing it. To copy a file from SBS
server
(shared folder) to local PC, even 15 MB, would take a while. Could
some
one
please suggest what could be the reasons??

Thank you in advance
