Thread: Slow Network Copying Speed , Help !!!

I have 2 systems .
System A ( Main System )
System B ( Bittorrent Box / File Server )

===============
System A Specs:
===============
OS = WinXP SP2
Athlon XP 3200+
ASUS A8V-VM
2x500 GB IDE
Normal Monitor + Keyboard & Mouse
==============
System B Specs:
==============
OS = WinXP SP2
Intel Atom 230
1x500 GB IDE .
Headless File Server

8 Port 10/100 Dlink Fast Network Switch .

I have shared a folder on System B , whenever I try to copy files from that shared folder to System A It takes 35 minutes to copy a 350 MB .avi file, however if I upload a file from System A to the shared folder on System B it takes less than 2 minute.

I have Tried the following

0) Both machines ping fine , <1ms

1) Transfer Mode on Primary IDE channel for HDD on Machine B is set to Ultra DMA Mode 5. [Read other forums and they stated that if the transfer mode is PIO then it could cause problems of slow transfer speed ]

2) I use high quality cat 6a cables (not 5a/e, 6a is rated for 10G Networks) , I have replaced the cables twice and checked them using high quality cable testers , all pass with flying colors.

3) Tried a brand new 10/100/1000 switch .

4) Tried switching from Auto to 100 Mbps Full Duplex and 10 Mbps Full Duplex

5) Formatted Machine A and B twice already just in case of issues with the OS

I still face the same problem , copying files from Machine B to Machine A goes at snail speed , I used DU Meter ( Bandwidth Monitoring Software )

Copying Files from Machine B to Machine A = Transfer Speed = 500 KBps
Copying Files from Machine A to Machine B = Transfer Speed = 9.8 MBps

Please Help , I have been googling this issue for over a month now ,

Copied within hard disk
is very different from Copy over a network.

HDD - HDD Copy Speed would be in Some Mega Bytes

Speed of Your lan is 100 Mega Bits.

So calculate.
