I have started my post from sentence 'almost no documentation'. Ok, I repeat my question in most simple form: cat /proc/meminfo MemTotal: 8197852 kB MemFree: 89764 kB Buffers: 16436 kB Cached: 3782336 kB What data stored in Buffers area, and what data a stored in Cached area? And what difference between them? If you know at least one article in kernels sources/Documentation folder, or anywhere in Internet, I'll read it gladly. I found nothing till this moment. -------- Original Message --------

I'm tempted to say that if you are trying to solve a specific problem relative to these aspects, you need to provide more information as to what your are seeing and what you are trying to do. If you want to generally refine your knowledge of such aspects, I would suggest googling a bit and reading some of the numerous articles on the subject or the kernel documentation, and perhaps get back to the list if you need any clarification. cj -- To UNSUBSCRIBE, email to debian-user-REQUEST@lists.debian.org with a subject of "unsubscribe".
