Titre: Swap disk - Force the kernel to use more RAM
Posté par: melodie le 12 janvier 2013 à 17:49:00
Hi,

This is a problem I have almost solved in antiX Openbox alpha1 by configuring zram, but it is only a turn around. Here is a good article on the Archlinux wiki about how to configure swappiness:
Citer
The swappiness represent how much the kernel prefers swap to RAM.  Setting it to a very low value, meaning the kernel will almost always  use RAM, is known to improve responsiveness on many systems. To do that,  simply add those lines to /etc/sysctl.conf:
 vm.swappiness=20
vm.vfs_cache_pressure=50


To test and more on why this may work, take a look at this article (http://rudd-o.com/en/linux-and-free-software/tales-from-responsivenessland-why-linux-feels-slow-and-how-to-fix-that).
