We have on average 100 connections.
Our system is a PoS System.
This customer has stores where you buy clothes.
In this chrismas times there is a lot of activity.
They sell a lot, and they do a lot of statistics.
The gab grows, when some users is just getting some statistics and previewing them on screen. Sometimes the user just leaves the computer and a transaction is running. If they do nothing, the program will after an hour close down the application (closing querys, commit transactions and disconnecting).
