does /proc/sys/vm/swappiness still work as expected?
# /proc/sys/vm# cat swappiness
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
