Asked By 60 points N/A Posted on -

Running Ubuntu on low physical memory can be hassle, in this case while loading Ubuntu starts using swap partitions that is hard disk to get enough memory requirement at a time this greatly reduces system speed. How can we work around this issue?

Ubuntu 12.04 Very Slow On Low RAM


The simplest solution to this problem is to reduce the swappiness value, it would take greater time to load Ubuntu with a low memory RAM but other performance issues due to swapping hard disk parts will not be there. We can achieve it by the following steps: a) After startup run the terminal and type cat/proc/sys/vm/swappiness to check the current swappiness that Ubuntu has set according to requirements.

b) The result is expected to be 60 which is the default value for Ubuntu, if a value of 60 is causing trouble we need to reduce it.

c) We have to open the file /etc/sysctl.conf using any default text editor and change the value vm.swappiness=10 or to any other desired value at the end of the file.

d) Save the file and try a reboot. Swappiness problem should be solved
