My questions: 1. Are the buffer cache and the page cache connected somehow? Does every write to the disk pass through the buffer cache and if no what uses does the bufer cache have now ... (kernel >= 2.4) 2. As i saw in the source code reading a page (if not in the page cache) is done from the disk directly ... have i missed something ? 3. Few articles i've read claimed that Buffer Cache and Page cashe are 2 cache levels ... is that right for kernel >= 2.4 ? Thanks alot in advance, Its very important for me to understand these things :) sushey __________________________________________________ Do You Yahoo!? Buy the perfect holiday gifts at Yahoo!
