transfering files between 2 computers.....painfully slow

One computer with xp pro is an ic7 p4 system (older) with a 3com 10/100 nic.
The other is new p5b conroe xp home and using the giga nic onboard. I have tried 2 routers, first a linksys befsr41 then a dlink 10/100 router both using different cables and even tried setting both systems to 100 full duplex..but transfering big files between them....home video up to about 700 800 Meg .....Max I get is 2M.
it bounces all over the place, from 300k to 6meg peak but averages about 2m when completed.

these systems are doing nothing but sending and receiving the one file. BOTH antivirus and firewall software are disabled on both...

Anyone have any ideas on whats up how to check and what to check?

thanks for any help
 
make sure you leave all your network cards to "autodetect" speed/duplex.

Forcing them to 100 full will make for really poor performance.
 
I tried it both ways hoping that might make a difference. I set it back to auto....
it made no difference, I thought about the router but neither have a choice on speeds
for the ports so I assume they are autodetect....it is really making me mad now.

I was shocked when I looked at the settings on this marvel gig adapter.
There must be 20-30 settings I didn't mess with them.

just for comparision what do others consider good speeds ?
I am using 10' cat5 cables and I can't think of anything else to try.



 
start at layer one, replace all cables with premade cables. Then I would move to layer 2....most SOHO stuff (iirc) will allow you to specify speed/duplex settings. If not, I would try and snag a different switch, at least for testing.

I think 8-10 MB/s would be considered good. I can certainly do this going between GbE and 100 Mb/s using a GbE switch on my computers.
 
Well I decided to see what cablenut said...nothing LOL
ok I backed up and ran cablenut on both systems.
Just to see if maybe it was some goofy setting.

I transfered a 200meg file from the pro machine to the home machine and still getting 300K to 2M bouncing like crazy.
BUT when I copied the same file from the home to the pro I get 10MB solid transfer.

Which machine is messed up? I dont know?
 
Is the hard disk on the XP Home machine nearly full, badly fragmented, or just slow/old? If so, delays writing files to the drive on that machine could be causing the slow and intermittent performance when moving files to the Home PC. Getting 10MB/s transferring files in the other direction means the network itself is probably OK.
 
no the home machine (windowsxp home) is on a new core 2 duo with new seagate 300G sata 2 hard drives.
There are 2 drives just for files...both have no more than 10 megs of files on them,in the system and I have tried reading
and writing to both ...same thing.

 
I suggest swapping out the 3com if possible. You might consider going to a GbE NIC. For testing purposes, you don't even need a GbE switch -- you could try it with a direct wire connection (standard cables should be fine for GbE).
