Hello

I'm planning to deploy otree via Heroku to conduct a large scale survey. What is the best configuration to do that?

More specifically, I'd like to be able to post *one* link to my survey in a popular online forum, which survey takers would then click on to be redirected to the Heroku app.  How should I set up Heroku / otree?

Should I create a single session or a room(?), with say 10,000 participants, and then just post the link to that session (or room) in the forum?  How many participants (concurrent / total) can otree handle?  Are there better ways to achieve this?

One constraint is that it's hard to anticipate the total number of survey takers, but it might be a few thousand and I don't want anyone clicking on the link I post to be turned away.

Thanks for any help!

I recommend to create a session in a room, and post the room-wide link.

See the notes on performance here: https://otree.readthedocs.io/en/latest/server/heroku.html#server-performance

Thank you for your quick response, Chris!

One more question, is there a benefit to running more than one dyno (i.e., turning "runprodserver2of2" in the attached screenshot)?

Thanks again!

No need. Just use the recommended configuration in oTree Hub's 'configure' tab.
