Uh at the very least Java is bad. the java programs we run take 4 gigs and burn my entire compute. Every1 used spring or guice and the di runtime, so tests are expensive for e2e with mocks. There’s no scrutable way I can run more than 2 or 3 on a standard laptop without burning out the thing.
You might want to check out Quarkus, Mirconaut, or Helidon MP. They do build time DI, and are more focused on performance and reduced resource usage. They are similar enough to Spring, and I believe Quarkus and Micronaut have an optional Spring compatibility layer that one can use. LLMs could help with migration if the codebase is well written.
Go can.
