It's not an app that buffers or caches stuff, it's the Linux kernel. it recognizes that certain things are being used multiple times and stores them in otherwise unused memory for convenient future access. It'll discard cached stuff or write to disk bufferd stuff whenever it needs to, should it need to free up memory in the future. You don't need to worry about this large amount of buffer/cache causing you to run out of memory,... it won't, as per above. > > Regards, > > Julien > > fred smith wrote: > > >On Sun, Feb 01, 2004 at 07:19:13PM +0100, Julien Tane wrote: > > > > > >>Hello, > >> > >>Can anyone tell me what in my computer takes so much RAM? > >> total used free shared buffers cached > >>Mem: 514592 390860 123732 0 23684 215796 > >>-/+ buffers/cache: 151380 363212 ^^^^^^ ^^^^^^ > >>Swap: 1020088 0 1020088 > >> > >> > > > >You asked: > > > > > > > >>So where are the 200M missing memory ? > >> > >>Can you give me a hint? > >> > >> > > > >Yes, look at the "cached" and "buffers" lines in your posting above. > >Those two total to around 235-240 megabytes. > > > >This is NORMAL.
