# Optimizing Amazon Linux 2023 for tiny EC2 instances: t3.nano, t3a.nano, or t4g.nano

## Summary

Amazon Linux 2023 consumes significantly more memory than Amazon Linux 2, causing severe performance issues on tiny EC2 instances with only 512 MB RAM. Two key optimizations can restore performance: disabling tmpfs for /tmp to move temporary files from RAM to disk, and removing zram-based swap in favor of disk-based swap to reduce memory pressure and CPU overhead from compression.

> yeah but, /tmp cannot be disabled at early boot state to take effect you need to do the steps described and then you need to reboot. It's sad that there isn't a method to disable this at early boot and the reason is that its pinned by system with files super early.
