I'm trying to switch from Heroku to Render but it is awfully slow compared to Heroku, my Rails project takes something like 1 minute to start after it has been shut down gratefully. Moreover, it breaks the CSS assets and uses the older assets instead of the latest ones. I do not why, it is a really small project and I have none of these issue on Heroku
Sorry about that. It sounds like you're on the free plan which is somewhat underpowered vs Heroku right now. Still, definitely not the experience we hope to provide and I'd love to learn more. Email in profile.
