ruby on rails is slow...or is it just me

i have made ruby on rails apps in the past but what turned me off is the applications were extremely slow when you first load them. i uploaded my app on heroku and i was wondering if this is only because i was using a free version of heroku?

In Heroku free plan you get poor resources for your apps (memory and CPU) and your apps go to "sleep" mode when they are inactive for some time (not sure how long, an hour perhaps). You can see the app is sleeping in your heroku dashboard. Waking it up (i.e. visiting it when it's sleeping) takes longer than a normal visit, but after that the app works well (considering the specs of the free server you get) until it gets back to sleep. There are also other considerations like using the newest version of Ruby, using Puma instead of WEBrick, doing other performance optimizations.

Anyways, the non-free plans are faster - better resources and they don't switch apps to sleep mode.
