Citing Lukas: does /proc/sys/vm/swappiness still work as expected? # /proc/sys/vm# cat swappiness 0 but scp-ing 2GB file causes many processes are swapped out due to increase of the file cache size. I think it is a regression in recent rc versions as I use 2.6.24-xx kernels on my new laptop from the very beginnig I have the laptopt and I did not notice such behaviour before. I have 1 GB RAM and I was coping a 2GB file from the network to the laptop. After the operation, 600MB of the swap area has been consumed. At the beginning of the copy, the swap area was empty. I have mapped ratio about 78 while scp-ing the file. Distress suddenly raises from 0 to 100. At this point, all the processes are swapped out. I guess it happens if scp is faster than the local disk which happens if I scp-ing over GE from desktop (with fast disk - and reading) to laptop (slow disk - and writing).

Yes. But it happens mostly if much memory is eaten by firefox and X server. It disappeared after I had upgraded to 2GB RAM.

There are too many further changes for this report to remain useful. Closing. If you have a similar problem with a current kernel please reopen or open a new bug thanks
