My organization occasionally runs workshops about our CF web application. 20 or
more people attend and follow along on computers in a lab setting.

We've hit problems when all the workshop participants are asked to do
something simultaneously, like check an option and hit "Submit." (a CF error
appears, but I can't remember the exact message)

Has anyone else out there dealt with a situation like this? I'm not sure if
it's a matter of the CF simultaneous connections setting or the database
connections setting (we currently do not have "Limit Connections" checked).

I did some research into increasing the number of simultaneous connections in
CF Admin, but the info said to set it to 2-3 times the CPUs available, which
would put the setting only at 12 maximum. I'm not sure if that would be
sufficient.

Thanks!
