I haven't got any response, yet. Perhaps somebody on this list can help me. What are the /proc/sys/vm/max-readahead and /proc/sys/vm/min-readahead are for? I find some mails about it in the kernel-mailinglist archive. But I didn't understand the concept behind these parameters. /proc/sys/vm/pagetable_cache is described in the kernel documentation. I don't understand, why do we have/need a per processor cache? Can someone explain more about that?
