Buffer Cache Stats from /proc/meminfo
Hi,

I am trying to understand the role of buffer cache in block I/O.
I am monitoring /proc/meminfo, my question is does the value of 0 for 'buffers', mean that any subsequent disk read issued by a process, would get the data physically from the disk, and not an allocated buffer for the block?
[Since, I can see the value of buffer parameter is currently 0?????]

Could someone elaborate on what does buffer=0 actually mean?

Hi, Is it possible to reduce the amount of buffer cache in the memory allocation of a Unix Server? If so where can I do that? Also, does buffer cache count as tied up memory, or will it decrease as more memory is requested by other programs. (1 Reply)
