The short version

  • Each has a real cost: Eclipse high memory consumption and CPU usage, especially with multiple plugins installed; Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • They diverge on capability: Eclipse covers Java development environment, Rollup covers Tree shaking.
  • Prices and features above were last checked on 30 August 2026.

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  • User interface considered outdated compared to modern IDE alternatives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

Rollup

  • Slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • Application concerns like dev servers and hot reloading are not its job, so app builds need Vite on top
  • Configuration for non-trivial applications gets verbose compared with tools that assume more
