Copying from a Western Digital 320GB to a Western Digital 320GB RE3

Wooohhaaa..

I take it thats a PCI-E adaptor? :eek:

Has the TCP/IP window size been changed?

Also has the ICS service been disabled?

Thanks

I need to get around to tweaking mine, oddly at 1st attempt Solaris wouldnt let me change the MTU on my pro1000

The other is in an ESXi box which looks easy to change. Might get one for my Desktop rather than the onboard NIC, but its splitting hairs really - not exactly slow at the moment

(~50-60mb/s)

HEADRAT · 5 Sep 2008 at 11:53

Yep PCI-E on both ends, haven't changed any settings

Ahh though so.

PCI card normally top out at 70MB/S ~ as they are sharing the bus with other bits and bobs.

Nice result though.

If its XP try this.

That's damn nice. I almost bought some of these cards a while back but didn't get round to it...

...I'm quite tempted again now

I turned off autotuning and now I'm getting 100% utilisation :eek:

netsh int tcp set global autotuninglevel=disable

Nice one

125MB/Sec ~ ?

damn nice

how much for the pair?

what was the speed before?

JonB · 5 Sep 2008 at 12:39

And I thought the 8MB/s was impressive on my lan at home! :-(

wasc · 5 Sep 2008 at 12:45

What network switch do you have? As thats impressive throughput for the switch as well as the network cards. Also you using Cat5e or Cat6???

I've seen pairs of these go on an auction site for less than £20.. Think it was about £15. It took a fair bit of me stalking the listings for a few weeks to see them go that cheap though...

You on Vista Sp1 there too?

I would also like to know which switch

Avalon · 5 Sep 2008 at 13:49

That's quick for the money!

HEADRAT · 5 Sep 2008 at 14:37

Nothing fancy switch wise NETGEAR GS105 ProSafe, using CAT5e, very short cables though

Yup, one machine is Vista X64 (SP1), the other is Windows Home Server

with a bit of storage
