My new gigabit network doesn't seem much faster then my 100MB at all

[goodstuff]

I wanted to speed up the connection between my two computers so I upgraded a bunch of my hardware to Gigabit ethernet. However it doesn't seem much faster at all (probably the same as 100MB). I read on a site that it should take about 30 seconds to move a 1GB file over a Gigabit Ehternet network, but it still takes me almost 3 minutes! I have a bandwitch monitor program and it seems during the transfer it ranges from 4-10 MB/s (is that good?). Am I doing something wrong, or are there Windows/hardware settings to change maybe???

My two machines are a) 733MHZ P3, 512RAM and b) 2.4GHZ P4, 1024RAM

The Gigabit stuff I purchased and installed:

1-D-Link DGC-100SD gigabit switch
2-Netgear GA311 gigabit PCI adapters
1-Belkin 50' Cat6 ethernet cable
1-Belkin 3' Cat6 ethernet cable

The 2 giga cables go to the switch, where I also plugged in my wireless' DSL router/firewall to feed both machines the internet as well.

Any help would be greatly appreciated!

Welcome to the reality of gigabit networking. I also have gigabit between some machines here. I get about 20% improvement when writing to the remote machine but 100% when reading from the remote machine. Since I was really upgrading to do faster backups, it's pretty much a waste. I suspect your slower machine will also be a factor, mine are a P4-2.4g and an AMD 2400+ that I'm doing the test with.

The bottleneck is probably inside the machines. Your hard drive might not be able to write that fast.

Wow, that kinda sucks since I wanted to use it for faster network backups as well.

Actually, I'm pretty sure my hard disks are not the issue. I can copy files locally between two hard disks at a 45-50mbyte/sec rate, so doing only one of those operations on that machine certainly should be as fast. I believe it's actually the SMB overhead on the network, but I don't have any idea how to fix it.
