Spring Boot on a low-memory VPS
This experiment tested whether StatLite could provide useful monitoring beside a representative Spring Boot application on a severely constrained VPS. It found that 256 MB RAM was unstable for the application, while at 512 MB RAM with a modest swapfile StatLite remained small and healthy and the controlled observation completed cleanly.

Spring Boot vs Quarkus under extreme memory pressure
A curated Spring Boot and Quarkus comparison using the same JDK 25,
Xmx80mprofile, and 512 MiB VM. Quarkus started larger but developed the smaller resident working set under pressure; a later constrained-VM run OOM-killed Spring, showing that the configuration could not reliably keep both JVM applications alive for an hour.
