Hit count: 523
vm.bdflush = 100 1200 128 512 15 5000 500 1884 2
vm.dirty_ratio = 20
vm.min_free_kbytes = 300000
That means that the MOST dirty data that can be in RAM is 20% and that there will always be 300MB RAM that linux CANNOT use to cache files right?
What I am trying to do is ensure that there is always room left for service to spawn and use RAM. I have 8GB of ram and hosting websites with PHP so I want to have more free RAM on stand by instead of seeing myself on 50MB of RAM free.
