How is everyone finding the performance of the on-board NIC? I am copying data between 2 unRAID servers (both Microservers) at 32mB/s currently. Was wondering if getting an Intel PRO/1000CT would yield any noticeable increase in network throughput.
Copying to the HP40L, via Gigabit Ethernet, I find that it will start out at around 110 MB/sec but then drops dramatically to almost half of that after about 2.5GB has been transferred, if a single file.
If there are several files then that initial transfer rate is maintained at 110 MB/sec.
At first I thought that the issue could be the capability of the onboard LAN but then I found...
If I am transferring a large (12GB ish in size) to the server and note its drop in transfer speed and I then start another transfer from the same PC to the same server, but a completely different drive, the total transfer speed of the two files is not that much short of the initial speed of the transfer.
Transferring FROM the server to my own PC (to a SSD) will sustain a constant (flat line) 100 MB/sec. There is no speed drop at all.
The HD's on the microserver are 5 x 2TB of WD Greens and Seagate Greens.
For me I tend to think that the limitations (drop in speed when transferring large single files to a drive on the server) is not down to the LAN, per se, but more of a limitation of the HD controller...?
I have not yet setup, apart from testing it, my N54L and so I do not know what the transfer speed would be from one server to another but I would have thought that you should be getting much more than you are, if you are wired at Gigabit speeds.
So I would expect over 110MB/sec transfer to my microserver.
