Best Optimization of Personal Pontoon?

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( etc. but heroku hobby is best option in my think.

so i optimized things, for example, gunicon worker - 2.
