RE: system event waits
1. If you have bug 1210242, then using timed_statistics=true will have a profound impact upon performance. Get a patch, and then go to 3. 2. If you use an HP-UX release older than release 10, then using timed_statistics=true will have a profound impact upon performance. Upgrade HP-UX, and then go to 3. 3. Otherwise, set timed_statistics=true at the instance level, and leave it set that way forever. In your first hour of using timing data, you will probably recover more system capacity than the timer mechanism will consume in a year.

Re: system event waits
setting it to true might have a very small performance impact. the impact of not having it set is that many of the statistics you gather for performance tuning are meaningless. If you need to get every possible millisecond of performance, turn timed_statistics on when you have problems and wait for the problem to recur or turn it on for a limited time, which will with luck encompass a relative sample of the transactions you run across --- BigP [EMAIL PROTECTED] wrote: Do you guys think making times statistic =true has any performance impact .
