Metabase first page load super slow

Hello everyone. We host the opensource version of metabase on Elastic beanstalk on aws, utilizing postgres. If no one uses metabase for some time, we notice a big first page load time almost 40-50seconds, from thereafter the metabase loads pretty fast for everyone.
Has anyone run into a similar situation, what could be the reason? We have enabled caching etc, but no improvement in this.

What’s the sizing of your Metabase server and the rds cluster?

Hey guys, for those who run into this, we were able to migrate to EKS and everything became night and day faster. Metabase with EBS is janky i guess

It’s not, it always depends on resources and tuning
