similar to: Asterisk & SMP: Is irqbalance Redundant on 2.6 Kernels?

Hello, Here is the situation. There is a machine with 3 intel gigabit card, 2 of them on PCI-X and in bridge, the 3rd is used only for management access. The machine is a dual Xeon 2.8GHz with HT. With 2.6.8 kernel from debian (testing) and htb with u32 on, i usually get about 30-40% software interrupts on CPU0 and CPU2, and without htb and u32, 10% less. Now, if I boot with 2.6.17.9 kernel,

Would it? I thought irqbalance is actually required even for native with

Hi All, If I turn off irqbalance xen/arch/x86/irq.c, does that actually stop XEN from balancing irqs across different physical cpus, or will that override the setting if there are too many interrupts and one of the cpus is overloaded. Example: i have 4 cpus and i have configured irqbalance= off, so there is no irqbalancing done by xen. Now if i have affintized all my physical interrutps to one

Hi All, We have a xen server and using 8 core processor.

I've got several SMP machines, some running CentOS 4.3 and some running Fedora Core 4. All machine are kept fully updated. A few are Pentium3-based and a few are Pentium4-based. They are all running the irqbalance daemon. The distribution of interrupts across CPUs is indeed kept balanced, yet even after months of uptime ps shows no CPU use whatsoever by irqbalance. This from a

I see the following on one of my new servers: -ts10::sedwards:~$ cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 2979045 2988620 87780075 87779501 IO-APIC-edge timer 1: 1 3 2 3 IO-APIC-edge i8042 8: 0 0 0 1 IO-APIC-edge rtc 9: 0 0 0

Has anyone had any compatibility issues with a TE110P card installed on a Dell Poweredge 1950? I noted the following error on the LCD display of the Dell Poweredge 1950: E1711 PCI PErr Slot 1 E171F PCIE Fatal Error B0 D4 F0. The Dell hardware owners manual states that it means the system BIOS has reported a PCI parity error on a component that resides in PCI configuration space at bus 0,

I am running irqbalance with default configuration on an Atom 330 machine. This CPU has 2 physical cores + 2 SMT (aka Hyperthreading) cores. As shown below the interrupt for the eth0 device is always on CPUs 0 and 1, with CPUs 2 and 3 left idle. But why? Maybe irqbalance prefers physical cores? My understanding, though, is that the even-numbered CPUs are the physical cores, with the

After updating to centos 4.3, I notice a failure in terminating irqbalance whenever i shutdown the system. Checking the services after the system reboot i see the error in irqbalance: "irqbalance dead but subsys locked" Can anyone tell me what irqbalance is and if it safe to disable it ? Why i dont see it in centos 4.2? Thanks in advance. Thai

Hi, I am after a feel of the throughput capabilities for TC and Iptables in comparison to dedicated hardware. I have heard talk about 1Gb+ throughput with minimal performance impact using 50ish TC rules and 100+ Iptables rules. Is there anyone here running large throughput / large configurations, and if so, what sort of figures? Regards Dan
