Hey @yaunghein,
This is actually not to do with the free plan. It is actually pretty fast.
There is however a problem with heroku and strapi’s compression method:
Implement the fixes, rebuild and push your Strapi to Heroku and it should be performing fine.
Read more from the docs: Heroku Deployment - Strapi Developer Docs
All the best!
