Playing Music Slows Vista Network Performance?
An anonymous reader writes "Over the months since Vista's release, there has been no doubt about the reduced level of network performance experienced compared to Windows XP. However, some users over at the 2CPU forums have discovered an unexplained connection with audio playback resulting in a cap at approximately 5%-10% of total network throughput. Whenever any audio is being sent to a sound card (even, several users report, while paused), network performance is instantly reduced. As soon as the audio is stopped, the throughput begins to climb to its expected speed. It's a tough one for users — what do you pick, sound or speed? So much for multi-tasking." -
MythTV Links Up with Program Guide Provider
Neil Campbell writes "As a long-time MythTV user, I found this announcement to be quite a surprise. A company by the name of TechnoVera has partnered with the founders of MythTV on an interesting project: A pay service for electronic program guide information rivaling that of Microsoft's Media Center. No more Zap2It surveys to continue using their free albeit basic service. The most important part of this is the fact that revenues from the service will be used to fund Open Source development; most notably MythTV. Registered Users will even have the opportunity to vote on feature enhancements that they would like to be incorporated into MythTV. I'm sure there will be some initial trepidation from the Linux community, but overall I think this should be considered progress. More attention and money for MythTV will result in a better product." -
Home Theatre PC Guide
Greg Ridder writes "For those of you who are interested in possibly putting together a Home Theatre or Media PC, I stumbled upon an excellent guide. It discusses basic hardware requirements, four software choices (BeyondTV, SageTV, MCE2005 and MythTV), controlling your cable or satellite set-top box and much more. Based on the research that I've done in the past, this is the most comprehensive guide that I've seen to date." -
Benchmarks Compared For Kernels 2.4.25 and 2.6.4
Josh MacLean writes "I noticed a link to an interesting article over at OSNews comparing performance of Linux kernels 2.4.25 and 2.6.4. While the workstation benchmarks are rather mundane, the server benchmarks (including Apache and MySQL) proved to be quite interesting. The rest of the Linux geeks might appreciate this. The comment thread that's linked on the last page is turning out to be relatively amusing as well." -

Linux 2.6 And Hyper-Threading
David Peters writes "2CPU.com has posted an article on Hyper-Threading performance in Linux. They use Gentoo 1.4 and kernel 2.6.2 and run through several server-oriented benchmarks like Apache, MySQL and even Java server performance with Blackdown 1.4. The hardware they use in the tests is border-line ridiculous (3.2GHz Xeons, 3.2GHz P4 and P4 Prescott) and the results are actually quite interesting. It's a good read as he even takes the time to detail his system configuration all the way down to the CFLAGS used while compiling the software." -

Hyper-Threading Explained And Benchmarked
John Martin writes "2CPU.com has posted an updated article about Hyper-threading performance. They discuss the technology behind it, provide benchmarks, and make observations on what the future holds for hyper-threading. It's actually an easy, interesting read. Of note, they'll be publishing Part II in the near future which will detail hyper-threading performance under Linux 2.6. Hardware geeks will probably appreciate this." -
SMP-Oriented Video Card Round-up
Jason Mitchell writes "I just noticed that 2CPU.com has posted a rather large video card round-up. They ran game and application benchmarks on a dual Athlon MP and Xeon workstation and also did some unique qualitative testing pertaining to s-video output quality. It's a good read." -

AMD 760MP Reviews Galore
Keith Whitsitt writes: "Well the NDA seems to be up on AMD's 760MP chipset, and several hardware sites have a review up. So far Anandtech, 2CPU, SimHQ, and Accelnation all have reviews up of this beast. It sure does look like the 760MP has shaped up to be all we expected it to be and more." Time-on-target hype. -
More Juicy Dual-Processor Goodness
ronmon writes: "I was cruising around bp6.com (I still want one) and happened to see a link to some pics of dual Socket A motherboards. It's in Japanese, so I can't read most of it, but this particular board caught my eye. It's a SuperMicro sporting two sockets and five DIMM slots, plus four drive connectors (IDE RAID?). Yummy!" And credulous reader Jim writes: "This one gave me a start when I woke up this morning. 2CPU.com has a screenshot of sisoft sandra scores from a Dual 1.53GHz (11.5x133)T-bird box. Apparently from an anonymous email. The scores are nothing short of amazing. Check it out." Grain of salt, remember. -

More Information on Total mPOWER?
Bingo Foo asks: "Many moons ago, I saw an article on some pretty neato sounding PowerPC daughterboards made to work with Intel Linux. To this day, I have yet to see a review of them (Say it ain't so, Ars...), or even a reasonably detailed explanation of how the cross-compiling and job execution work. In a somewhat exhaustive Web search, I found more questions and speculation than answers. All of the specific applications mentioned are rendering and other 'dumb' SIMD processes. It's difficult to tell just how versatile these boards might be. Has anyone shelled out the $6k for one of these things and are they willing to share their experiences with the rest of the world? In particular, I wonder if this might come in handy for some Monte Carlo codes that we run where I work, where raw flops are more important than communication or memory, and the parallelism is MIMD.""Just an explanation of the programming/compiling/execution process would be nice, and inquiries sent to the manufacturer have resulted in sales-type replies which weren't technically helpful."
