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.

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

<p>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.</p>
