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  • User interface considered outdated compared to modern IDE alternatives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

Splunk Enterprise Security

  • Splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
  • Splunk publishes no rate for Enterprise Security and directs buyers to contact a pricing expert
  • UEBA, SOAR and automated threat analysis require the Premier edition rather than Essentials
  • The platform underneath can be billed by ingest volume, workload or activity, so the total cost depends on a pricing model chosen at contract time rather than a list price
