However, if you start one emerge with a set of dependencies, then start another and they clash somewhere in the middle, portage has issues. That is where the locks would kick in I guess. I would also imagine that portage could emerge the same package twice too. If one instance of emerge doesn't know what the other instance has already done, then the second one could emerge it again. Doesn't emerge do all the calculating at the beginning and runs with that until the end? I am using the -j option for the first time now. I'm updating KDE. It seems to work fine. It doesn't scroll all the stuff like with a regular emerges but this new rig is so fast, I can't read it anyway. I did have a package to fail and it spit out the error for me to read. I agree, using --jobs is the best way to do this. It works really well if you have a fast multi-core CPU. I wish I had got me a 6 core one now. ;-) Dale :-) :-)

Emerge would skip the locked packages during calculating dependencies and building phases and possibly wait for them to install. Just a naive idea though. Cheers, P.

KDE. unpack/configure/install takes up a significant amount of time for KDE Putting reply in just one post this time. This is a discussion now and not a technical problem. The package that failed had nothing to do with it building more than one package at a time. For some reason, it didn't have one of the patches downloaded. I guess it was a failure between here and where the mirror is. When I restarted the emerge, it found it and no problems from there. It would have done the same thing if I wasn't using -j is the point here. Tthis was a KDE upgrade, it saved a LOT of time. Most of the time only a couple cores are really working especially when they are smaller packages. When using the -j option, all 4 cores were running and was pretty busy all the time. At one time, it was doing 20 packages at once. I also noticed the hard drive light was pretty steady too. All in all, using the -j option seems to have saved a lot of time here. This is a fairly new install so I can recall how long it took to install KDE the last time. This was much faster. Just reporting a real world experience here. I wish I had got a 6 core CPU now for sure. Maybe later. Dale :-) :-)

The difference is that with shift-middle click, or with vim that cannot talk to X, the terminal sends the selected text to vim as normal input (as if you would type it) and thus its get indented/formated/etc..

[gentoo-user] Compiz-Fusion does not show windows border
Hello mates, I'm running Gentoo ~amd64 I try to install compiz-fusion, following the wiki, everything seems to be fine, but when I try to run compiz-fusion, it works but not so well, because does not show me windows border, also I put compiz-fusion to use indirect rendering and loose binding but none of this works. I'm stuck. Here is my emerge --info: http://tinypaste.com/43af1 Extra: INTEL GMA VIDEO_CARDS= intel I'm using i915 driver (enabled modesetting on intel by default) What is wrong??

One or two packages (like OpenOffice) will fail and need -j=1 to emerge. Otherwise no noticeable drop in desktop responsiveness. I have not set up portage niceness so it runs with default value. Given the above what shall I set --load-average as? Not sure, I tested last night with a value of 12 and my system was still responsive. It depends, I think, on how well your system handles higher load. The best suggestion I can give is to actually test with values and see how well it responds. -- Joost

I have 4Gbs and it was up to about 3Gbs at one point and using some swap as well. I'm hoping to max out to 16Gbs as soon as I can. May upgrade to a 6 core CPU too. I wonder how much faster it would be if the work directory is put on tmpfs? With 16Gbs, that should work even for OOo. Btw, if you're using more instances than the amount of CPUs, the result will be slow-down. With the default kernel scheduler, best if amount of CPUs + 1. (On a 4-core, that's -j5). I just used -j with no number. It worked fine and I played Solitaire and checked my email while it was running. The only thing I noticed was it using swap. That could slow things down but otherwise, it worked fine. I do have the nice and ionice settings in make.conf tho. That helps a lot for sure. Without those, it would likely slow down a lot. Which settings do you use for that? -- Joost
