Massive disk i/o on memory reach %70
Previously system became unresponsive when RAM usage reached around %70.
It was because of massive disk I/O operation, presumably to swap disk. I
tried to tweak swapiness factor and it didn't affect anything at all on
both sides of the extreme. I decided to delete the swap partition
altogether, since my system has 4GB RAM. The swap partition was about 6GB.
It is yet no difference. It seems in whatsoever configuration, %30 of
memory should always be free. This is not a space rocket command and
control system, so I don't understand this cautious policy. Can anyone
please explain? Is there any other setting I could tweak to get the bar of
memory usage up to say %95?
Thanks
