Hello, I just installed WHS with all the updates on a new custom-build box. When I attempt to transfer files from my NAS, an HP MV2020 Media vault, I get extremely slow transfers, 1 MB/sec or less. I am copying files from the HP NAS, which is connected via ethernet cable, to my WHS, obviously also connected via ethernet cable, via my wireless laptop. The wireless router is within 5 feet of all 3 machines. Am I missing something? Is there a BIOS setting I need to set? Here are some of the components of my WHS: MSI 785GM-E51 AM3 mobo Western Digital Caviar Green WD5000AADS 500GB 32MB Cache SATA 3.0Gb/s 3.5" Hard Drive (system drive), SAMSUNG EcoGreen F2 HD154UI 1.5TB 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive (2 x storage drives). Please advise. Thanks.

I'm guessing you're using Wireless G? If so, 1-3MB/s is about average. And about the only option at that point is to tweak your wireless settings.

Agree with the above, assess peformance from a cabled machine before looking at wireless.

OK, I am getting ~ 8 MB/sec with my wired connection :( Just how fast should I be going? I was told by someone if I used a Gigabit switch that my speed would increase tremendously, at least for the wired machines. True? Right now I am using the gateway provided by my ISP (a Westell D90-327W30-06). HELP!

8MB/s is reasonable for EtherFast (100mbps). however on gigabit, that really depends on a lot. Make sure all network hardware is capable of supporting gigabit first. That means the client computer NIC, your router, and the server NIC. After that, it comes down to tweaking. Generally disabling "Checksum offloading" helps.

100Mbps ethernet provides 11MB/s, I would expect you to be getting that with large files assuming you have anything vaguely modern at both ends TBH. Gigabit might give anywhere between this and 110MB/s depending on the depth of your wallet...

I picked up a Netgear Gigabit 8 port switch and installed a Gigabit ethernet card on my desktop. All the machines have Cat-6 cable between them (there is still a Cat-5 between the gateway and the switch which, I believe, should not make a difference). I am now getting 15-20MB/sec but I should be getting a LOT faster rates now. Any ideas?

The typical bottleneck on Gigabit networks has everything to do with HD i/o capabilities.. Look at improving your disk i/o and you should be able to see somewhere between 20-50Mbs network throughput depending on your HD's..

Can someone advise on how to improve HDD I/O? Thanks!

[J1mbo]

What HDDs does you server have at the moment? What is the spec of the client PC that you're using for the tests? Don't get concerned about cabling, Cat-5e is absolutely fine for gigabit.

OK, now getting 30-50 MB/sec! I got that once I went into the BIOS of the server and enabled LAN onboard RAM.

Hi: I have an mv2010 and tried to modify my server BIOS but couldn't figure out how. Could you please supply some detail on the steps that you followed to enable LAN onboard RAM? Thanks

I am uncertain what steps I took other than look for: "enabled LAN onboard RAM" or something to that effect. Sorry I cannot be more specific than that, but I am away from my WHS for several days and cannot access it.
