Jorma,
Performance tuning is a complex subject. There really isn't a list of
10 things to watch for. Every system is different.
I would (attempt to) summarize tuning by these five steps:
1.) Have a capacity/performance target in mind. If you don't know
where you're going, how will you know

In any case, I have to do this

The ten most important performance items to monitor are your ten most

Right On!
