Struggling With Low Speeds < 15MBps Over Gigabit

I suggest you give up on them for now

Yeah, I'm thinking that may be a good idea.

Also, the LAN test results appear to be wrong, since your drag-and-drop measurement is 3x faster.

Yeah, that does seems strange. I wouldn't mind, but I paid for that program too. :(

Try the NAStester and let us know what it reports in both directions.

Well, I've just ran 'NASTester' on a 'Mapped Drive' and the results were as follows:

ReadyNAS:
Jumbo Frames: OFF
MTU: 1500

Test1:
Default 400mb File (5 x Loops):
Write Average: 26.9 MB/sec
Read Average: 102.9 MB/sec
Achievement unlocked: 100MB+/sec read speed! :thumbsup:

Test 2:
4000mb File (2 Loops)
Write Average: 25.6 MB/sec
Read Average: 90.9 MB/sec

Can you check the NAS network stats, and see if you are getting transmission errors when writing to the NAS?

Not sure if this is normal, but the 'TX Packets' & 'RX Packets' are increasing steadily when the ReadyNAS is idle and NOTHING is being transferred!

For instance, I clicked the 'Show Errors' button as you suggested and after a timed 60 second period, I clicked the button again and both Tx & Rx figures had increased:
TX Packets: 70
RX Packets: 152

Normal?

Anyway, I did as you said and recorded the before & after network errors either side of the 4000mb file transfer mentioned above.
Strangely though, the write phase was pretty quick, but the read phase, which is usually quicker, took absolutely ages (time wise), but the reported transfer speed was similar to other tests run earlier .

The results of the network errors is as follows:

I also strongly recommend re-enabling the broadcom NIC, and seeing how the speed compares. Also, try the ping test with the broadcom and see if you can get 1460 working with that.

I'll have to do this tomorrow.

Just a thought, but would having a 'Wake on Lan' option set up on my router cause any problems?

Thanks again for the pointers. Learning summat everyday! :D
