I agree with hacketta1

"Do you have a performance problem? Do you have evidence that those wait events are causing the performance problem?"

Unless you've done some benchmarks, rounding up the nearest suspects is not a good idea.

And benchmarking your system at startup is meaningless.
Until you've got the system cranked up to represent a typical database profile you are probably wasting your time. Until that shared pool and buffer cache are in full swing then it just isn't worth looking at any stats at all.
