I'd like to try this out, but I get a 404 error when trying to download?


Works for me. Perhaps I will rename the download, as the "ö" might miake troubles.

Does this link work now:

What's also interesting is how much slower the supposedly faster (in clock speed) prescott core is than the northwood core.

Careful, different versions of GCC there. (not arguing with you about prescott vs northwood - I'm an AMD fan, I know nothing about Intel)


gcc shouldn't matter much here. I tested it on an Athlon64 X2 w/o using athlon specific optimizations. I don't think this generic code would make a big difference on P4.

Ok :D :D :D

I think I finally got it right!!!!

I just got the whole system rebuilt, and DAMN!!!!

It is fast!!! I can open almost anything from the main menu in less than a second on the FIRST start!! Second start is instant!! And the only thing that I'm using is -bdirect, and -hashvals, I know that they are in main portage now, but it was YOUR effort nxsty that started it..... THANK YOU!!!

Linux has always started programs slower than just about everything else out there until now....

Dont get me wrong, it RUNS programs pretty damn quick, but it always STARTED programs pretty damn slow.... That is until now....

Thanks Nxsty for the overlay.... It makes a BIG differance... This improvement makes gentoo even better.....

Glibc 2.3.6-r3 has the patches so you don't need my glibc overlay. You just need to enable them in the ebuild, but I guess you've already done that. Binutils 2.16.1-r1 has an older -Bdirect patch but lacks hashvals and dynsort so it's a better idea to use a overlay for it with the latest stuff.

Yeah I figured it out. I copied the glibc folder to my overlay folder and hacked the ebuild to enable those patches. I did use your binutils overlay though. And if you saw my thread about my troubles you'd see I got everything to work. I'm now have a fully stable and working system using gcc-4.0.2-r3, glibc-2.3.6-r3 w/Bdirect & hashvals patches, binutils-2.16.91.0.6, portage 2.1_pre4-r1.

If you guys have problems with Cairo, using nxsty's binutils overlay there is a patch in bugzilla that fixed it for me.....

I added a new snapshot. It now also builds with -DNDEBUG=1 if you don't have debug in USE (perhaps the stable ebuilds should do this also?). This ebuild also merges all the changes from 2.3.6-r3.

PrakashP: I hope this fixes your performance problems.

Could someone tell me where to get glibc-2.3.6-branch-update-20060224.patch.bz2 for the latest overlay? It doesn't appear to be on any of the mirrors but perhaps I missed a note telling me where to get it or something?

Edit:
Oh never mind, it was one of the stupid cudlug servers getting stuck in pasv mode and giving me grief. I found the main telia server from the ebuild and downloaded it manually. I didn't realize it was part of the overlay rather than from the official 2.3.6 glibc at first :oops:

I'm using nxsty's binutils-overlay (2.16.91.0.6) and a hacked glibc-2.3.6-r3 (to get -Bdirect and -hashvals). I had problems emerging cairo. I found a fix here which directed people to a reported bug at freedesktop.org (Bug#5136).

Solution:

  • Copy /usr/portage/x11-libs/cairo to /usr/local/portage/x11-libs/cairo
  • Edit /usr/local/portage/x11-libs/cairo/cairo-1.0.2.ebuild, and add this to line 39 (it's an empty line):
    Code:
    sed -i -e '/INT_/d' pixman/src/pixman-remap.h

  • run an ebuild digest on the file:
    Code:
    ebuild /usr/local/portage/x11-libs/cairo/cairo-1.0.2.ebuild digest

  • emerge -av cairo

Ok.. I was about to post the below text, but I figured it out. Anyway, why not post it for those who think they have the same problem, and like me, can't read :roll: :oops: :lol:
===== blind-joffer =====

nxsty, this is not quite on the point, since I'm using 2.3.6-r3 with -Bdirect and -hashvals, but I thought I'd ask it here anyway, since you included those in your old glibc-overlay...

I'm just not getting the scores I'd supposed to get...:
Code:
armour ~ # bin/memcp 2000 1000 1048576
Memory to memory copy rate = 744.766541 MBytes / sec. Block size = 1048576.


Any clue? My entire system has been emerge -e system && emerge -e world, and I actually did a new emerge -e system last nigth because I thought I had screwed something up (which I hadn't.. I was just blind and not able to read the errormessage good enough...)
===== blind-joffer =====

First - my numbers now:
Code:
armour ~ #  bin/memcp 2000 1000 1048576
Memory to memory copy rate = 2175.091309 MBytes / sec. Block size = 1048576.

2175 Vs 744. Quite an easy match.. And thats without compiling anything on my system..

Oh well, thats a very minor lie.. You see, I compiled the binary as I normally do (which is not quite often, not counting the emerges of course):
Code:
gcc memcp.c -o memcp

I started to read nxsty's old Glibc overlay with amd64 performance patches! (obsolete) and what do I see (which I had forgot):
nxsty wrote:
...
*AMD64 optimized string routines.
Increases memory copy performance for AMD64. The improvements can be seen with a small test-program, memcpy.c, which is attatched to the bug (compile it with -O at least).

With the glibc 2.3.5 currently in gentoo:
isidor ~ # ./memcpy 2200 1000 1048576
Memory to memory copy rate = 1291.600098 MBytes / sec. Block size = 1048576.

With glibc 2.3.5 + amd64 optimized string routines:
isidor ~ # ./memcpy 2200 1000 1048576
Memory to memory copy rate = 2389.321777 MBytes / sec. Block size = 1048576.

That's an improvement of over 1000mb/s! Suse 9.3 and 10 also gives about 2300mb/s out of the box.
...

So, to my self and perhaps others: READ CAREFULLY (and of course remember it for later :wink:): "(compile it with -O at least):
Code:
gcc -O2 src/memcp/memcp.c -o bin/memcp
did the trick, resulting in 2175MB/s :D

hello all,

i just finished updating glibc to glibc-2.3.90.20060224 and it is working GREAT on my system it's never been faster. THANK YOU NXSTY. but im curious about something, i forgot to add sys-libs/timezone-data to package.keywords, and once the compile finished i had two config files that needed updating, hosts.conf & nscd. so i ran etc-update and -5'ed 'em both. then i rebooted and had clock skew (so i modified both files and unmodified them to set thier time right) both config files were 7 hours off, my timezone was changed from mst to utc and i was unable to reset the timezone until i added sys-libs/timezone-data to package.keywords and did emerge -uD world which updated timezone-data from 2006a to 2006b. once that was done everything was fixed. and as im somewhat new at this (heh i wouldn't even have this cool toolchain if it wasn't for nesl247 and the conrad guides) i'm curious as to why that happened? did it have something to do with the version of timezone-data? or is it a bug, and do i need to watch out for it in the future?

Has any one noticed that -Wl,--as-needed in the ld-flags seems to have no effects on any packages using these ebuilds?

As I understood, the flags are used for other packages, but not glibc or binutils (binutils enables a bunch of those flags).


But does anybody know if there is a difference between -Bdirect and -Wl,-Bdirect? If so, I would appreciate any hints what the differences are.

thx!

--as-needed is reducing the number of library being linked by testing if they are actually needed at run time. THis will do not much for the speed the program is running but will reduce staruptimes and potentiona breakage because of changed libraries. Check with ldd before and after building with --as-needed.

Both are the same. But when invoked via gcc you need to add -Wl to tell gcc its a linker flag (correct me if i'm wrong here).

hm...but when I try to compile amarok-svn with -Bdirect (no -Wl prefixed), gcc tells me to use -fPIC, with -Wl,-Bdirect as LDFLAG it works without any probs.
