Hi Gabriel,
on my Macbook Air, Java 8 is factor 1.3 slower:

Java 6:
ImageJ 1.51j15; Java 1.6.0_65 [64-bit]; Mac OS X 10.10.3; 8554K of 3000MB (<1%)
Batch mode: 5
Normal mode: 3165

Java 8:
ImageJ 1.51k5; Java 1.8.0_101 [64-bit]; Mac OS X 10.10.3; 39MB of 3000MB (1%)
Batch mode: 2
Normal mode: 4264

Best regards, Norbert
