I using pontoon in several project (almost 10+), 100+ peoples in Heroku Hobby Instance. it’s looks great, and i satisfaction of it.
Problem is very small, heroku’s hobby time is 1000 hr, but almost month my pontoon is exceeded hour.
several think is going - honcho, Kubernetes(https://bugzilla.mozilla.org/show_bug.cgi?id=1513104) etc. but heroku hobby is best option in my think.
so i optimized things, for example, gunicon worker - 2.
and another things of optimized pontoon?
