Re: XP very slow to write data in a W2k share

Hello,
Alex, you can put all interfaces to auto speed and duplex or force it in a
specific speed/duplex by going in your network interface properties
(computer manager / devices manager / network cards or something like that,
i'm working on french OS).
For the switch, it depends on your equipment.
Mak, in my case, i've tried many combinations, the server and the W2k wks
are forced to 100/full, the switch interfaces are forced to.
For the XP wks, i get the betters performences by forcing everything to
100/full... So I it done, but do not solve the issue...
I'm waiting for other ideas, and no, it is not the QoS bandwith reservation
that is limiting...
Thanks,
Laurent

I also have similar problems with accessing files and printing from W2k
accessing a XP workstation with its printing resources shared and files
shared!
Where do I find or how do I set "Put_all_interfaces" that you talk about
below? How do I know what it is at the moment?

Hello,
after many times exploring newsgroups, forums and Ms KB, without any
answer, I finaly submit you this case...
I certainly missed something....
Here is the case:
- 1 W2k sp4 server, AD domain member, 2 interfaces, 1 in AD side
(172.30.xx.xx), the other on a private subnet (a
workgroup/192.168.xx.xx).
- 2 W2k sp4 workstations in the private subnet
- 2 XP sp2 workstations in the private subnet, i have to replace the
W2k
with it....
These computers are link by a switch with all interfaces forced to
100Mb /
full duplex.
A local account is created on the 5 computers, as local user on
w<orkstations, and to grant permssions to the shares on the server.
On the workstations, a software reads files on the share, an operator
modify them, and they are rewrited on a another directory of the share.
Under W2k, everything seems to be ok, but under XP, the software
becomes
very, very slow.
The hardware does not seems to be the trouble... The workstations are
all
some Dell Precision Workstations 2Ghz for W2k and 3Ghz for XP, with
intel
chipset for the lan.
When using "netperfs" to test the lan, i get between 75 and 85 Mb/s for
a
100Mb/s link, so that's not so bad.
When testing FTP transfert, i get some equivalents résults under W2k
and
XP.
As soon as we use the windows copy system (event in command line), the
XP
performances are falling.
I made some testing with command line tools for the resources kits:
- Creatfil, to have dummy files (512Ko, 1Mo, 10Mo, 100Mo)
- Timethis, to have running times.
Here is a shot details of tests:
- upload from server to XP => Ok (>68 Kb/s)
- download from XP client => Ok (>65Kb/s)
upload from W2k client => Ok (>60 Kb/s)
upload from XP client => NOT OK! (<35 Kb/s)
I saw many KB acticles, talking about SMB trafic (C/R transact - KB
330929), or many other KB articles (885198 / 301952 / 311169 / 831129 /
825433 / 326826 / 328890 / 812661...), but no one seems to answer to my
question.
Some news posts are talking about "Webclient" service, but it is not
significant.
I have to change theses W2k worstations, but it is not possible with so
poor performances, so any help would be appreciated
Thanks,
Laurent
