Swappiness not working

rng · 01-11-2012, 10:46 PM

I am using ubuntu 11.04 natty and I have 512mb ram. I have set the swappiness value to 10 (confirmed by command 'cat /proc/sys/vm/swappiness'). However, whenever the memory usage becomes more than 50% or so, the swap starts getting used and system performance goes down. Please help.

Read the section where Andrew Morton says:
"I'm gonna stick my fingers in my ears and sing 'la la la' until people tell me 'I set swappiness to zero and it didn't do what I wanted it to do'".
