Dear all,
I have 128 MB RAM and 128 MB swap right now. What if I double my RAM and disable swap altogether? What can go wrong for the same setup?
When you run out or physical RAM, the system will try and page some things out. You can end up paging things out even if you are not running many/large applications. Sometimes the system runs more efficiently with some things you don't use swapped out and more RAM for disk cache. My advise would be to up the physical RAM you have, and leave the 128MB swap as is. If you disable swap completely, you may end up with things getting killed by the OOM killer in the kernel if it for some reason run out of RAM. Someone else may have an idea of when swap starts becoming a non-issue, like at 16GB or 32GB of RAM.. :) Rgds, -- Anders Karlsson <anders@trudheim.com> Trudheim Technology Limited
