Linux and 802.IQ

nyway is Linux 802.IQ compliant? Is Linux 2.2 or just 2.4. How long has 802.IQ been around and how widespread is it. Is Solaris compliant. How about NT/ Win 2000. Robert Cohen TLTSU, Australian National University. - To unsubscribe from this list: send the line "unsubscribe linux-kernel"

Terrible elevator performance in kernel 2.4.0-test8

2.4.0-test, the max_bombs value has been eliminated so I can't change it. I was hoping that that meant that the algorithm had been improved. Unfortunately, the benchmarks don't show any improvement. -- Robert Cohen Unix Support, TLTSU Australian National University - To unsubscribe from

[Demo program]: Poor elevator performance in 2.4.0-test9pre6

gle threaded benchmark thats slowing things down. As I understand it, the elevator should be dealing with the interleaved nature of the writes. This seems to be working ok for reads, but it doesnt seem to be working properly for writes. The source can be found at http://tltsu.anu.edu.au/~robert

Re: Benchmark results for elv_test

f, then its not clear if performance problems found are in the kernel or in the unusual libraries used. Robert Cohen Australian National University J. Robert von Behren ([EMAIL PROTECTED]) write >Looking over your test program, I don't think you are actually testing >the elevator alg

Question: Status of VIA chipsets and 2.2 kernels

e DMA disk transfers between channels. Some reports say these only occur with Western digital disks. The 2 athlon boards listed include an onboard promise IDE controller. So I should be OK if I use this for disks, right? Any other problems I should know about? -- Robert Cohen Unix Support TLTSU
