Re: [tycho-user] tycho compiler optimization

[Stéphane Vaucher <svaucher@xxxxxxxxxxxxxxxxxxx>]

String concatenations are typically a JIT optimization that are not done at compile time, but at runtime. Thus, the compiler used by tycho, whether jdt or Hotspot should not affect runtime performance. For example, when using Hotspot, the optimization option does absolutely nothing. I suspect that JDT does something similar (maybe it reduces the size of the .class files though).

Hi,

I can face a significant performance loose with tycho-compiler-plugin compared to Eclipse compiler. I've done profiling my application with YourKit and can monitor complete different results. I think tycho-compiler doesn't optimize string concatinations. So if I'm right, how do I enable these optimization? I tried it in pom file with optimize tag set to true, but that didn't help. Thanks for your help
