Plugin support for gcc in RHEL/CentOS? I had looked at that list before posting this and, at least from the descriptions, none of those seemed to provide support for plugin usage with gcc. |

Plugin support for gcc in RHEL/CentOS? I would like to do it at least on RHEL 6 and hopefully RHEL 5. Specifically, I'm trying to build and use odb and it requires plugin support for gcc. |

High CPU usage with CFS? It appears that there's something wrong with the link and the correct one is here, but I'll give those workarounds a try and see if they help performance. |

High CPU usage with CFS? @Nils Wow, that's really interesting. Assuming that this was an issue introduced in 11.2 and not just "first reported" in 11.2, then it appears that it's not CFS but a change to CFS that caused the issue. Do you know if the performance has improved or been resolved in a later release of SUSE? |

High CPU usage with CFS? @Nils Really? According to kernel version listed in the wikipedia article, CFS was introduced between version 10.3 and 11.0 (based on CFS begin merged in 2.6.23). |

High CPU usage with CFS? @rozcietrzewiacz If you take a look at the Ubuntu bug, I ran with a vanilla kernel built by Ubuntu and the linux-ck one is built from a vanilla kernel with the BFS and -ck patches applied, so I think that's about as close to a vanilla to vanilla comparison as is easily possible. I don't have access to a machine to build kernels on, so that's the best I can pull off, but the test code is available so I would love for someone to do some more fine grained testing of linux builds to see if they can isolate the issue. |

High CPU usage with CFS? @rozcietrzewiacz That was the intent of the BFS results on Ubuntu 11.10 (the last set of plots). It showed some improvement but not a complete resolution. You can also see the bug that I opened against Ubuntu here. |

High CPU usage with CFS? Moving the images to dropbox so they'll be visible, and just linking to the updated code |

High CPU usage with CFS? I'm new to the whole RedHat bug thing, so that may have been something that I did (or didn't do) when creating the bug that did that, but the only update I've heard so far is an update to a parameter that makes it behave better with hyper threaded processors, but no real fix yet. |
