Funny thing about questions like this is that there's no real way to map the
answer to such a question back into something that you can actually use in
the real world. The problem: what exactly is a transaction? The number
you'll get by using statspack is derived this way: number(transactions) =
number(commits). But, from the business perspective, what is a transaction?
For a given business, it may range from a .2-second form validation to a
3-hour report! It makes no sense to talk about the characteristics of an
"average transaction" on a system unless it has homogeneous workload-which
is a situation that arises almost never in nature.

Bryan,
You can run statspack snapshots every hour, then run reports comparing each
hourly snapshot and it will show you the transactions/sec in the top "Load"
section. No init setting required for this, but you'll want
timed_statistics=true in order to gather other useful stats.
Regards,
Brandon
