Navision 3.70 with its own database simulate Performance

Hi,

is there a possibility to simulate the working of 100 users (clients) on my server with a performnace software.
I want to see when my navision 3.70 system is going down.
I want to simulate different Navision Users working for 100 Users.

For example:
Can I let run when a User starts his Client a recorder which records every action from that user for one hour (or longer) and then I can without User action make that again. And that action for 100 Users.

Is there a possibility with a tool to let 100 Navision Clinet run a make some performance on my system?

Thanks for ideas!
