Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Eclipse

  • High memory consumption and CPU usage, especially with multiple plugins installed
  • Slow startup times and performance degradation with large projects or many open editors
  • Requires configuration of eclipse.ini file to optimize heap sizes for adequate performance
  • User interface considered outdated compared to modern IDE alternatives
  • User base fell from 39% of Java developers in 2024 to 28% in 2025, indicating market decline

Turbopack

  • Effectively coupled to Next.js; using it standalone is not the supported path
  • Younger than the alternatives, and ecosystem plugin support is narrower than webpack’s
  • Benchmark claims have been contested publicly, so measure on your own project rather than trusting headline numbers
  • Being Vercel-driven ties its roadmap to one company’s framework priorities
