Networking

The Windows 2000 Driver Development Kit (DDK) includes a useful LAN testing utility called NTttcp. We used the NTttcp tool to test Ethernet throughput and the CPU utilization of the various Ethernet controllers used on the Intel motherboards. We set up one machine as the server; in this test, an Intel X58 system with an Intel EXPI9402PT (PRO/1000 PT) Gigabit LAN card. Intel's Gigabit LAN solutions have a reputation for providing fast throughput and is a logical choice for our Gigabit LAN server.

On the server side, we used the following Command Line as suggested by the VIA whitepaper on LAN testing:

Ntttcpr -m 4,0,‹server IP› -a 4 -l 256000 -n 30000

On the client side (the motherboard under test), we used the following Command Line:

Ntttcps -m 4,0,‹client IP› -a 4 -l 256000 -n 30000

At the conclusion of the test, we captured the throughput and CPU utilization figures from the client screen.

Network - Throughput

Network - CPU Utilization

Our network throughput test indicates how well a particular controller design from Realtek, Marvell, or Intel performs instead of being indicative of true chipset performance. This also holds true for the CPU utilization results, though this test can also be influenced to certain degree by the BIOS code and chipset interconnect design.

The CPU utilization and throughput results slightly favor Windows 7. The good news is that we did not see the horrible networking performance that plagued Vista up until Service Pack 1. In actual transfer tests of various file sizes across the network, Windows 7 was the fastest, with XP Pro x64 very close behind and Vista usually trailing by a percent or two. In practice, few if any users will notice a difference, even if they have the requisite Gigabit hub, as storage performance frequently bottlenecks the actual transfer rates.

What about Battery Life? USB Performance

    We have an additional article coming with ATI vs NV, IGP, netbook, and we will delve into storage and networking with a Promise NAS server. I just received Win7 specific network drivers so I will complete the multi-task testing shortly.

    Thank god for the media center improvements. ClearQAM support FINALLY, after hearing almost nothing for years. Better codec support is also extremely welcome.

    While Vista’s adoption has not been a failure, it hasn’t necessarily been a success story either.


    What? Can you please explain to me how you define "failure" as it pertains to Microsoft's OS? Doesn't it have about 5% penetration in business? You don't call that failure? You can't define the term based on consumer products - consumers who buy off the shelf PCs have no choice in the matter.

    For what it's worth, my definition of failure would be "Businesses won't take it, and the consumers situation is so bad that the majority of OEMs are still shipping XP as the default desktop OS".

    Vista didn't go well for Microsoft, but the fact that the vast majority of computers being sold are using Vista and the guys in our forums are using Vista near-exclusively is proof to me that it clearly wasn't a failure. A late bloomer perhaps, or maybe a lame duck.

    Businesses can be extremely slow to change, with some still using Win2k. I doubt XP had that much market penetration in business after ~2 years either. If MS left Vista around as the newest OS for several years it would probably have more, as XP does now. I'd say the larger failure is that consumers were making buying decisions on computers based on which one they could get with XP.

    I'd guess the automatic window resizing can probably be disabled (I like my windows the size I set them, thank you very much) but how about adding text labels back onto the taskbar icons and not merging them together? If I have multiple Firefox windows open, there is probably a reason for it and I don't want to keep having them merged.

    Also, with this pinned icon being the taskbar icon thing, how do I launch a new window of whatever program that is? Firefox again, for example, will clicking it allow me to launch a new window? Or would I have to maximize a current window and then use the menu to launch a new window?

    left click and drag up or shift click

    The task bar can be set to several options. The default is "Always combine, hide labels". The second option is "Combine when taskbar is full" - that's the one I like, and you get text labels up to the point where the windows merge. The final option is "Never combine", which gives text labels and behaves in a WinXP manner.

    Anyone get a display driver to install on a HD 4770 under W7 RC?

    9.5 in a couple of weeks.. could not get the 8.612 from yesterday to work right, it would load through the manual process, but performance was way off compared to Vista 64.
