Hi Paride > Back in the day I asked upstream their take on irqbalance usefulness with > newer kernels, here is their reply: > https://github.com/Irqbalance/irqbalance/issues/151
Thanks for this and the other extra pointers. The Debian bug was referenced before, AFAIC it is mostly around a) the kernel got smarter in many cases (true) b) bad in virtual environments (we already removed it from those) And in that discussion the upstream comments (it is good to see that they are still convinced of their code) revolved around: c) There should be no conflict with running irqbalance (with the new kernel) d) The kernel policy is driver centric (irqbalance has a full picture) Both - as I read them - are more arguments to keep it than to remove. But as all other, not with enough data to make it a clear yes/no. As I said much earlier in this case, I feel this is system and workload dependent and hence there will never be a clear generic yes/no. The best we can achieve is finding sets (like images used in virtual environments - or as suggested desktop systems) and drop it being the default there. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/1833322 Title: Consider removing irqbalance from default install on desktop images Status in irqbalance package in Ubuntu: Confirmed Status in ubuntu-meta package in Ubuntu: Confirmed Bug description: as per https://github.com/pop-os/default-settings/issues/60 Distribution (run cat /etc/os-release): $ cat /etc/os-release NAME="Pop!_OS" VERSION="19.04" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Pop!_OS 19.04" VERSION_ID="19.04" HOME_URL="https://system76.com/pop"; SUPPORT_URL="http://support.system76.com"; BUG_REPORT_URL="https://github.com/pop-os/pop/issues"; PRIVACY_POLICY_URL="https://system76.com/privacy"; VERSION_CODENAME=disco UBUNTU_CODENAME=disco Related Application and/or Package Version (run apt policy $PACKAGE NAME): $ apt policy irqbalance irqbalance: Installed: 1.5.0-3ubuntu1 Candidate: 1.5.0-3ubuntu1 Version table: *** 1.5.0-3ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu disco/main amd64 Packages 100 /var/lib/dpkg/status $ apt rdepends irqbalance irqbalance Reverse Depends: Recommends: ubuntu-standard gce-compute-image-packages Issue/Bug Description: as per konkor/cpufreq#48 and http://konkor.github.io/cpufreq/faq/#irqbalance-detected irqbalance is technically not needed on desktop systems (supposedly it is mainly for servers), and may actually reduce performance and power savings. It appears to provide benefits only to server environments that have relatively-constant loading. If it is truly a server- oriented package, then it shouldn't be installed by default on a desktop/laptop system and shouldn't be included in desktop OS images. Steps to reproduce (if you know): This is potentially an issue with all default installs. Expected behavior: n/a Other Notes: I can safely remove it via "sudo apt purge irqbalance" without any apparent adverse side-effects. If someone is running a situation where they need it, then they always have the option of installing it from the repositories.
