How To Clear Swap Memory In Linux

24/11/2014 · Re: Can't clear my inactive memory on Linux Centos Post by chemal » Mon Nov 24, 2014 8:18 pm I recently cured a longstanding problem with machines getting slower and slower over time by disabling 'transparent huge pages'.

  • Like any other operating system, GNU/Linux has implemented a memory management to clear RAM cache manually, whenever a process is eating away your memory.
  • This is managed on a delete-on-write basis, so if the copy in RAM is updated the blocks in swap will be released. If the swap space is needed for something else, which it won't be at the moment as you have plenty free, it will of course be released for that use.
  • The Swap Cache. When swapping pages out to the swap files, Linux avoids writing pages if it does not have to. There are times when a page is both in a swap file and in physical memory.
  • Do I need more swap? No, disk caching only borrows the ram that applications don't currently want. It will not use swap. If applications want more memory, they just take it back from the disk cache. They will not start swapping. How do I stop Linux from doing this? You can't disable disk caching. The only reason anyone ever wants to disable disk caching is because they think it takes memory
