Does "dead" code hinder Java application performance?
dead-code, java, performance
Solution
It could affect a few things...
- Size of the application
- Memory used when application is running
- Decreased performance on package scanning (if applicable)
Problem
I just installed the Unnecessary Code Detector for Eclipse and ran it on my project. I see a lot of so-called "dead code". Although, from an organizational standpoint, it makes sense to remove dead/unnecessary code, it got me thinking: Does dead code actually hinder a Java app's performance?!?! To me, if code is truly "dead", it never gets executed, so I don't see how removing it (again, except for organizational/housekeeping/code cleanup purposes) could ever improve performance.
