Hi people, I got Centos 4.3 on a 1GB Pentium IV machine. The output of free ------------------- $ free total used free shared buffers cached Mem: 1026896 573848 453048 0 2988 131712 -/+ buffers/cache: 439148 587748 Swap: 1052248 137568 914680 ------------------ There is plenty of free ram, but the kernel prefers to swap unused pages to disk. And later I have to wait for them to be unswapped, the Desktop looses its promptness - annoying. In win2k and winXP there is a registry key property which prevents swapping while there is still RAM. Do you know whether I can achieve the same in linux? Best regards! alex
