Re: Waits 8i vs. 9i??

There is microsecond granularity in some of the columns, but not all platforms support microsecond timing.
So some of these are centi seconds multipled by 10000. There are ofcourse exceptions (like Compaq Alpha, that suppports msec clocks).

There are more wait events in Oracle9i but the top wait events shouldn't have changed. Just think about all the functionality changes and the code that supports that.
May be Oracle9 is 50 percent larger than Oracle8i.

Oh, btw Oracle8i supported already microsecond timing on some platforms but that was converted to centi seconds. Just to be consistent.
