| |
Forgive me if this seems a really dense question, but with the new unified page cache, is the buffer cache completely obsolete? There is still a number for it in top and vmstat (which comes from /proc, I suppose) which seems to increase practically without bound as block devices are read. I assume the number is bogus now.
Also, I am trying to understand how much difference this actually makes as far as memory usage is concerned. On a "typical system" (yeah, right ;-) how much duplication of cache was really occurring. And is this significant for low memory systems as well as large memory ones?
Thank you for any enlightenment.
