[TriLUG] tuned tunings

[Lee Fickenscher via TriLUG]

It's for Mongo, which is why I was looking at the Oracle profile.
Mongo has a set of suggestions for tuning and it's all over the place.
I suspect it can all be done with tuned, which is part of their suggestion,
so I'm trying to get it all in there.
They want ulimits, blockdev readahead, atimes, and max procs modified. They
also want transparent huge pages disabled. I already have the THP and
readahead set. Now I'm looking to get the procs and atime in my tuned
profile.
