So if your source based package manager supports adjusting its niceness, do not hesitate to make use of it especially if you are one like me who has 15 apps open on 15 different virtual desktops while compiling the latest version of Openoffice and listening to punk rock from juK without any skipping. I do this when I don’t need to use the computer and I’m compiling large packages. On the other hand, when I need all the CPU power I can get for compilation, I switch to console mode, shutdown X/KDE/whatever, add -j4 to the make option, and I set portage ( the package manager) niceness to -20. In fact, from my observation, they have none. But compiling CPU intensive packages have almost zero effect on UI responsiveness. This undoubdetly may increase compilation times. In Gentoo’s portage, for example, there’s a option to set the niceness of portage (package manager). This is particularly useful for source based distros with an organized package management system. Use it with caution though, I’ve heard it’s not a good solution. I can’t overemphasize the speed boost in responsiveness to my GUIs. This trick is particularly pertinent for source based distro users, for obvious reasons.ĭecreasing the niceness of X. There are just two things you need to do improve responsiveness of your gui while under heavy load such as compiling. Also, its supposed to allow the kernel to make better use of larger numbers of processors. On the server side, the new scheduler is supposed to enable the usage of huge amounts of threads (hundreds of thousands) because the CPU time used by the scheduling algorithm is not proportional to the number of threads. This makes a big difference in how fast the system feels under load.

It solves a problem that really shows up in Windows a lot - an interactive task that needs to do disk I/O (like launching a program or opening a file) often has to wait a long time for a background task’s I/O to complete. The new I/O scheduler helps a lot here too. It is a huge success on this front: I can run multiple compiles in the background and not even notice an impact on GUI responsiveness. On the desktop side, it is meant to increase responsiveness, through the integration of the preemptive patches. I use 2.6 on my laptop, and I don’t get audio skipping even with multiple compiles going on in the background.Īlso, the new scheduler is supposed to address a lot of things. If you use KDE, aRts should get started with real-time priority anyway, so you should not get skipping problems.

WinXP does the same thing - it gives a +8 priority boost to any process using an audio device, while BeOS has special scheduling priorities for audio processes. That’s exactly what the priority mechanism is there for - to tell the kernel which processes are more important than others.

And don’t get the idea that giving the sound-server a higher-priority is somehow cheating. MP3s skipping hasn’t been a problem for me ever since the preempt patches came out, and I used 2.4 on a PII-300 at the time. You have to give the sound-playing process a higher priority if you don’t want your MP3s to skip.
