John,

Statspack shows global aggregate data. It means that the numbers you see are numbers from *all* the sessions running on the server during the one-hour time you mention.

If you are not seeing any specific performance problems, I would not worry about it.

HOWEVER, there may be times when it is the cause of a problem. For example, let's say that you have a job (or user action) that has to finish in 5 seconds and it is not meeting that target. For example, it could be running for 6 or 7 seconds. If this same job is the *only* one that contributed to the calls to "SQL*Net message to client" (or even if it contributed most, say 2secs out of the 3secs), then it might warrant further investigation.

Again, if I were in your position, I would not worry about it if there are no specific problems that you see. BUT if there are performance problems, then I would trace (10046) those user actions and take it from there.

James
