OK i've now added CFQ in grub and now i have everything that you have there.
Is there anything else i can do? i'm a performance junkie
I've got my whole system prelinked and using NPTL. i need more!!!!!! |

Well the raid requires money and a PC
But ReiserFS4, i'm gonna wait a bit longer
I have important work on my laptop. Anyway once i buy a PC.
I'm in Uni at the moment. First year so money is a bit tight.
I think CFQ is slowing my startup down quite a bit.
I might cancell that, leave the default on, i think AS (or is it AP?) is default. _________________ http://www.mooktakim.com

Here I'm using :
gentoo-dev-sources 2.6.5
ati-drivers 3.2.8
glibc 2.3.2-r9
My system worked perfectly. Added "nptl" to the USE flags and recompiled glibc. Now X only work at 640x480@85 and cannot change resolution via <Ctrl+Alt++> or <Ctrl+Alt+>
Somebody having the same issue? Any ideas? _________________ La PDA de tungsteno |

Only problem I've encountered with NPTL-enabled systems was with MySQL...but that's MySQL's fault. |

Sorry for the off-topic question (is there such a thing in Gentoo Chat lol ), but what does CFQ do that isn't already there by default ?
I'm running the gentoo-dev-sources 2.6.5-r1 on my machine with NPTL. Is the CFQ not the default for the 2.6.x kernels ? Where do I add commands to test CFQ running on my machine ?
I use Gentoo as a desktop (Gnome 2.6), and I'm still trying new things to see if get better 'snap' or FPS in games etc |

When changing glibc always so this:
Then if you want to switch back after upgrading you can do:
Code: | emerge -k /usr/portage/packages/sys-libs/glibc-2.3.2-r1.tbz2 |
I always quickpkg stuff before I upgrade or remove a package. It can save alot of time later, especially with large packages and a slow machine. _________________ For since in the wisdom of God the world by its wisdom did not know God, God was pleased to save those who believe by the foolishness of preaching. |

A warning to nvidia users: Remember to re-emerge nvidia-glx and nvidia-kernel after building glibc with nptl.
I didn't do this and as a result x froze on the next boot, and I had to do a hard reboot (which is a bit of russian roulette with reiserfs I have heard. My barrel was empty though ). Then followed booting into windows, downloading a recent livecd, burn it, boot it, check fs for corruption, disable xdm in my installation, reboot, re-emerge nvidia-glx/kernel. Then things worked.
As for xmms, it segfaults on exit, but otherwise it works fine, don't know if this is nptl related since I haven't run xmms from konsole in a while... |

TenPin has it right with quickpkg. glibc±nptl are the only binpkgs I have in my /usr/portage/packages.
The only problem I have had is that mono 0.91 will not compile properly with gcc 3.4.0 under glibc+nptl. But merging the quickpkg either side of the mono emerge fixes it. _________________ No more cruft

I had the same problem. Without nptl both of them work perfectly! Peace. _________________ conflict -> contact -> combat |

Hey, I've been using NTPL for about a month now, no problems. Just a question though, are any of you with NTPL problems using prelinking? |

I'm using NPTL, and have been for quite some time on multiple machines. I also use prelink and I've never had any serious issues with it and NPTL. |

well, ive been using nptl from the get-go (stage1 about 3-5 months ago) and it has never had a problem, the best way to switch to NPTL is to reinstall from stage1 and use it from the very beginning.
If you are upgrading to NPTL make sure
1) you are using 2.6 kernel
2) 2.6 headers (emerge -C linux-headers ; emerge -av linux26-headers)
3) have a .tbz2 of glibc incase it does royaly fuck up the system, glibc can be very touchy sometimes (you have been warned) just emerge the known good version of glibc and try again once u get enough balls
4) you might want to use gcc 3.4, i have been using 3.4 since i set up this computer and no problems, i dont know if gcc3.3 has any issues with nptl, but look into it.
anyways.. nptl has gained me alot of performance when im multitasking, thinks emerge ultra quick and my desktop never has a laggy feel, so i am happy. im just about to play around with different kernel patchs to try and make my desktop load faster.

I'll echo the sentiments of other folks here. I've not had any trouble at all with nptl since installing it.
Incidentally, installing it is really easy and pain free. There was a minor bug a little while back that gummed up the works, but it was quickly resolved.
Best,
Alex |

I did echo sys-libs/glibc ~amd64 >> /etc/portage/package.keywords
and USE="nptlonly" emerge glibc

If you plan to use a XEN kernel then NPTL is a bad idea because XEN "emulates" it very slowly. |

i'm using nptl but today i had my first problem due to nptl.
When i want to rip a DVD with dvd::rip i have a problem when i rip the titles/chapters of the DVD.
I recompile glibc without nptl and it works great..
Can you use transcode with nptl enabled ?

I have no problem ripping dvds using dvd::rip with nptl enabled. You may need to run revdep-rebuild or re-emerge dvd::rip or both. It's hard to tell if you don't post errors and such.

I had the same issue but the ~x86 version of transcode has been working with nptl so far for me. |

Sounds pretty shitty how some apps break when you increase posix compatibility. I guess this raises the question, how broken is the current threading model. _________________ Jabber: goalieca[AT]jabber.fr
