I have a Django app running on Heroku. At the moment I only have 1 dyno. One of the urls generates a pdf from database values and this takes about 4 seconds. Since I only have 1 dyno, does it mean that while the pdf is busy generating, my dyno can't respond to any other requests from any other users?
In other words, how many open requests can Django/Heroku handle at a given time?
