Func_odbc mysql simultaneous connections

i normally use asterisk to interface with mysql via func_odbc to let users give input and store them.
A have had no more than 15k records on a single DB.
Now i’m facing a challenge…
I have a request about a DB with 250K records and i thinks i should provide enough trunks…
Let’s imagine a limit of 15 concurrent calls…asterisk is able to manage 15 simultaneous connections with mysql?
is there a way to simulate simultaneous calls and updates on DB?

I would think the limit would be imposed by MySQL. You can simulate VoIP calls with the SIPP tool or with another instance of Asterisk and call files.
