I have a D-Link gigabit router DGL-4100 and two PC's connected to it with onboard Realtek gigabit ethernet adaptors.

When transferring files between the PC's using FTP the fastest transfer speed I can get is 26MB/s.

Should it be faster? What would be the bottleneck? The integrated ethernet adaptors?

PC's have resonable specs, quad core, lot's of memory, SATA2 HDDs etc.

Hi there,

I dare say your hard drive are the bottleneck, although you should be able to get at little better than 26mbps.

Have a read of this article which will explain why hard drives are the common bottleneck in gigabit networks:,2321.html

Agree hard drive speed with be the bottleneck most likely.

You could benchmark the drives in each system with hdtuen or crystaldisk.

I have not seen over 30megabytes/sec between machines, whereas the 2 drives in one machine will go to about 60-65 on the windows 7 copy speed meter thing, and it doesnt seem to be cache since thedrive light goes off a couple of seconds after the dialog disappears.

Ahh esata ;)

Tried HDTune and got an average transfer rate of 70.1MB/s.

I'll have a read through that article. First thing to try might be connecting the machines together directly to eliminate the router being the bottleneck.

If you want to see what sort of actual network capacity you can get between the two PC's, iperf is great for this.

If it shows really high speeds then you can start to look at your disk I/O and other things.

I hate you.

setting your MTU to 9000 and ensuring RFC1323 is enabled will most likely help as well. On a PC at work that I couldn't get any better than 250mbit out of when doing an FTP transfer, I was able to get 800mbit+ using iperf which shows the hard drive to be the bottleneck as others have mentioned.

When I have LANs here we run via an 8 port gig switch and get about 40mbps on average via DC++.
HDD is the usual bottleneck tho as others have mentioned.
