How many people can connect to one experiment at once?

I have less of a coding question and more of a general question about Pavlovia. Are there limits to how many participants can do a study at the same time on Pavlovia or should it be able to handle large traffic for the same experiment?

I think there can be issues if there are multiple people starting an experiment during the same second, However, once started there shouldn’t be a particular limit for the number of concurrent participants. There may be a limit to how often the shelf can be called.
