Question
Network slow between XP Pro and Windows 2003 server
I have been pulling my hairs for almost a week trying to resolve this slow network issue. Transfer between both machines are painfully slow.
1. Windows 2003 is run off on AMD Athlon 64 3500+ with 1GB ram. I have initially used Belkin gigabit card (PCI). Now it has been replaced with USRobotics High Performance 10/100/1000 Mbps Desktop/Server Networking PCI card. Server is running on Raid 1 using Promise TX4200 and two 400GB SATA-150 disks.
2. Windows XP Pro is run off Intel Pentium 4 3.6Ghz with 1GB ram. I initially used asus's built in dual gigabit network. Now it is replaced with same brand/model as server USR card.
3. I have replaced the old Belkin gigabit 5 port switch with 16 ports Netgear gigabit Switch model GS116.
4. I have tried some MS workarounds via registries without any success.
5. I have set both machine to Full Duplex 1000 mbps. (on asus built in gigabit didnt offer 1000 option, only 10/100/auto which is why I replaced with USR card).
Best speed I am seeing is approx between 50-71mbps via xcopy in dos.. but worse in file explorer. Most files are over 100mb each in size.
I am unable to find any workable fixes on net. 500 points to anyone successfully solving my issue (I would give 2500 if the system lets me!).
Thanks in advance.
Richard

both machines IP are static, 192.168.0.2 (server), 192.168.0.150 (workstation), 192.168.0.1 (router/DNS).. I dont believe it is DNS issue since I can communicate with server using \\server\d$ from workstation without any issue execpt for minor delay initially when connecting for login.
I already using new Cat 5E cables..

check your throughput between machines using Qcheck by IXIA. It's a free "software lanalyzer" http://www.ixiacom.com/pro
Install it on both the server and the workstation.
Then from either one, open it and choose localhost to "other machine name" and choose throughput test. Put the kb up to something like 750 or so.
See what it shows.
Also, if your switch and NICs support it you could enable jumbo frames which would speed everything up on big transfers. Just know that it needs to be enabled on ALL devices connecting to that switch. for more info on jumbo frames support you'll need to check your NIC user guide.
The throughput result is apprx 242 Mbps using 1000 in feild. I repeated this many time and got pretty much the same..
I have enabled the jumbo frame but it seem to be pretty unstable connection between 2 machines.. I couldnt "remote desktop" to server fully.. I disabled both and it restored normally.
Yeah, Jumbo frames is tricky to implement.
http://kbserver.netgear.co
Since your netgear switch is "unmanaged" you won't really be able to hard code the ports to Gigabit.
I would try setting both machines to auto negotiate. Then after setting this, look in the system log on each machine and it should tell you if it had any errors negotiating the connection speed.
This may change your throughput considerably.
simple solution
on client
(tcpip properties)
make prinary dns server the server ip
add server ip to wins (and enable netbios over tcpip)
lmhosts (C:\WINDOWS\system32\drive
SERVER-IP SERVER-NAME #pre #dom:YOUR-DOMAIN
hosts (C:\WINDOWS\system32\drive
SERVER-IP SERVER-NAME
SERVER-IP SERVER-NAME.DOMAIN.com
should do the trick.

Cleaner, I have tried jumbo frame without the switch by using crossover cable between PC and Server.. It does improve about 100mbps, not too much. Since I need the switch, i have disable the jumbo frame on both ends.
Shep,
I have tried this, but since I do not have DNS/WIN server installed on server yet, which would cause no access to outside internet. But during this test using your config, it didnt help at all.
UPDATE:
Upload and download seem almost matched speed but upload QOS is really horrible compared to download from server is stable traffic which is why upload is much slower. One thing I noticed: During upload, server's Raid LED was flashing rapidly while download didnt. This made me wonder, is the raid drive limiting this? Maybe increasing write buffer?? How?
See network traffic graphic (Green = upload, red = download) at http://richardreed.com/net
-Richard
Shep,
I have installed AD (included DNS) and also installed WIN.. I now noticed very stable upload QOS with avg of 115mbps and about 108mbps download. But far from good gigabit traffic, I would thought to expect to be faster than 400mbps for both directions.
What exactly does using server DNS/WIN helps it? And any suggestion on how to improve throughput?
Thanks,
Richard
The card I am using is Promise 4200TX, see spec at http://www.promise.com/mar
Two harddrives: Model Number: ST3400832AS Capacity: 400 GB Speed: 7200 rpm Seek time: 11 ms avg Interface: SATA 1.5Gb/s Seagate Barracuda 7200.8 drives with SATA and native command queuing enabled. Using two Promise Hotswap 1100 trays.
I downloaded Performance test 6.0 software and ran full disk test. Here the result:
Sequential Read: 59.0 MBytes/Sec
Sequential Write: 11.2 MBtyes/Sec
This is very disappointing benchmark.. Any suggestion to speed it up?
Richard
Not much you can really change that will make much of a difference with the existing hardware. 10k and 15k rpm scsi drives would make a difference AND a dent in your wallet... :)
RAID always introduces a little overhead as well.
Also, your switch may have something to do with the speeds as well...I looked at the specs and they aren't bad, but you may test putting a machine with a crossover connected straight to the 2003 server and see what kind of speeds you achieve. The switch may not have the memory/proc/buffers to handle what you are trying to get out of it.

I forgot to add: The server is FRESH INSTALLED and patched to SP1 and latest patches.. I havent activated the Active Directory yet. No AV or anything. Reason for this, I want to rule out any weird installation issues.
