Hello, The XEN kernel in "XEN RELEASE-4.0.1" is shipped with the following config parameters: CONFIG_HZ_1000=y CONFIG_HZ=1000 At many blogs and forums there is a discussion that the CONFIG_HZ parameter should be changed to 250 HZ or 300 HZ. We will operate a DomU and the Dom0 with the same 1000HZ Kernel. Is this setup possible and recommended. How high is the performance cut-off? Which option is more s...

Hi all :) I''ve tested this and having a cpufreq that slows down the CPU affects the rate of HTB. My ondemand cpufreq governor scales down the CPU frequency about 40% and this is more or less the slowdown the rate suffers, 40%. Any known way of dealing with this without having to disable cpufreq? Thanks in advance :) Ra?l N??ez de Arenas Coronado -- Linux Registered

Hi, I have some servers that are dedicated to do meetme conferencing. From some previous test i concluded that I need to use dahdi_dummy as it is more accurate. If I did use the core timers in dahdi (not loading dahdi_dummy) I got bad quality in the conferences and dahdi_test showed 99.6% as worst. I thought maybe the issue as bad hardware for the timing or something else. But today I

Hi, On 64 bit centos 5.6 I have virtualbox 4 and 64 bit elastix latest. Since yesterday cpu utilization has been constantly peaking 65-75%. Hardly 1-2 concurrent calls. No other activity on server. Top shows asterisk on top. Its quad xeon server with 4 gb ram. Any suggestion where should I start and how should I go about with my investigation. Thank you and have a great weekend. Sans

Hi All, I am using the script below to limit download rates and manage traffic for a certain IP address and testing the results using iperf. The rate that iperf reports is much higher than the rate I have configured for the HTB qdisc. It''s probably just some newbie trap that''s messing things up but I''m buggered if I can see it. The following script is run on the

I tried booting the paravirt patches on a real machine to see what would happen. It had worked OK under qemu, so I thought it would be worth it. It seems to boot OK, though perhaps fairly slowly, but once it hits usermode it gets into trouble. When starting udevd, the startup script runs MAKEDEV, which seems to get stuck in an infinite loop in userspace. It eventually gets past that part
