Some sysctl parameter change questions.

Some sysctl parameter change questions.

Looking through some tuning documentation about sysctl values as related
to Oracle and other DB tuning bits, I noticed that the following don't
exist anymore, and was curious where or if they were moved.

/proc/sys/kernel/inode-max
/proc/sys/vm/freepages

In coincidence with this info, I was curious if anyone has tweaked the
following and if it makes any difference, with regard to performance:

/proc/fs/pagebuf
/proc/sys/vm/pagebuf
/proc/sys/vm/pagebuf/max_dio_pages
/proc/sys/vm/page-cluster
/proc/sys/vm/pagetable_cache

Just FYI on this. I'm not having any particular problem per se, I'm just
trying to tune for my DB as best I can and watch the performance stats
of various operations. So, please don't be hindered, if you have
anything to say about these items, that I didn't specify a problem.
There isn't a real *problem* ATM.
