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? |
