Oh, in fact it is quite useless anyway.
I read somewhere here, that the process are not really started parallel.
There was a patch for that, but it didn't work for me.
Sometimes perhaps the bootscripts will be updated, sometimes.

Don't install stuff you don't need
Use USE flags correctly to control that. If you want to compile something, and it tries to install KDE or something else not needed, look at /usr/portage/profiles/use.desc to see if there is a USE flag, then, for example, do this:
| Code: |
#/etc/make.conf
...
USE="bla blah blah... -kde"

use NPTL threads (for the many "non Stage1" users)
only for 2.6 kernels
| Code: |
add "nptl" to the USE flags
emerge -C linuxheaders
emerge linuxheaders26
emerge glibc
|
have fun
What does this do? I'm not really sure, but after that, I had to glue my PC to the table 
? |

I jsut checked out emerge -avp depclean.. basically to see the difference between the gentoo-own emerge cleaning and the dupecleaner I just upped (https://forums.gentoo.org/viewtopic.php?t=15032). I think the depclean is extremely dangerous... it actually wanted to remove my par2cmdline, hotplug, openoffice, and much more I use every single day. I wonder how emerge comes to think these progs are useless? -
nevertheless i was able to free quite a lot of space (about 2gigs/30 packages) which where complete useless because they were older versions of packages I have currently installed with the script from https://forums.gentoo.org/viewtopic.php?t=15032 (or http://www.gargan.org/linux/#mozTocId100001 ) ... oh and make sure you check out thi util https://forums.gentoo.org/viewtopic.php?t=260866 (cleaned some other packages for me...)
A little warning: ALL TOOLS MAY DAMAGE YOUR GENTOO BE CAREFUL! better you have some lost space than you ruin your whole system... |

This is the error I get when I try to emerge the gentoolkit. Should I start sweating?
Dan
>>> md5 src_uri  gentoolkit-0.2.0.tar.gz

!!! ERROR: app-portage/gentoolkit-0.2.0 failed.
!!! Function dyn_unpack, Line 678, Exitcode 127
!!! Failed to create dir '/var/tmp/portage/gentoolkit-0.2.0/work'
!!! If you need support, post the topmost build error, NOT this status message.
emerge the gentoolkit package and then run revdep-rebuild [/quote]

In fact, now when ever I try to emerge ANYTHING this comes up. Any help would be REALLY appreciated.
Thanks

You need a patched kernel for that.

Basically you've removed an important library, and I think almost everyone has done this at least once. Fire up the LiveCD and copy the missing libs across until you stop getting the error, then emerge acl and finally add "acl" to your USE flags so it's not removed again.
Now why acl isn't in the default USE flags to begin with I have NO idea...

For your acl problem:
http://dev.gentoo.org/~avenj/bins/
holds binaries of important system packages that you may use to repair your system.
There is a README at that location that you should read and follow.
acl and probably attr are what you will probably have unmerged by that depclean.
once your system is repaired add acl to your USEflags in make.conf.
I hope this helps.
Regards

I say try using the CFQ schedular in the kernel it made a huge difference for me i was emerging 6 things at once with very little slow down.
If xorg is alittle slow call fc-cache some times the font cache get messed up this will fix it most of the time.

How-to slightly improve 3D-Acceleration in games and/or X (NVIDIA-Cards)
First check what your current graphic card supports: | Code: | $ cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: PCI device 10de:01e0
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
Registers: 0x1f00421b:0x00000312 |
If "Fast Writes" is not supported, but you are sure that your motherboard supports it, this problem is probably caused by a wrong setting in the BIOS. So if necessarily, check your Motherboard's instruction and activate it then in your BIOS. After that, edit /etc/modules.d/nvidia to activate SBA and Fast Writes. | Code: | nano -w /etc/modules.d/nvidia && modules_update
uncomment this line: options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1 |
Now we will finally edit the xorg.conf file. Go then to the section "Device" and insert the following three lines: | Code: | Option "AGPMode" "8"
Option "AGPFastWrite" "1"
Option "NVAGP" "2" |
The first option, "AGPMode", sets your graphic card to 8x AGP instead to 4x, which is default. The second option, "AGPFastWrite" is to play it safe that FastWrites will be used by your X-Server. I'll explain what the option "NVAGP" means in the next step.
NVAGP or AGPGART?
There are two different AGP-Drivers. First, there is NVAGP. It will be installed with the Nvidia-Graphics card driver. The second one, AGPGART, is the Kernel's native AGP Driver. Now you'll ask which of these ones is the faster one. But I don't know it . I tried both of them but my results were the same. In my opinion, I'd advise you to use the Kernel's AGP Driver, especially if you're often compiling the latest, high-patched kernel-sources. NVIDIA's NVAGP is known to (maybe) break then.
The option "NVAGP" accepts four values, these four values mean the following: | Code: | Value Behavior
----------------------------- -----------------------------
0 disable agp
1 use NVIDIA's internal AGP
support, if possible
2 use AGPGART, if possible
3 use any agp support (try
AGPGART, then NVIDIA's AGP)
|
In my example on the top I'm using AGPGART. To be sure that the new options have been activated, kill your X-Server and reload your NVIDIA-Module. | Code: | | # /etc/init.d/xdm stop && rmmod nvidia && modprobe nvidia |
Afterwards start your X-Server again and type this line here into a terminal emulator of your choice to see if your system works with the new options. | Code: | cat /proc/driver/nvidia/agp/status
