Interesting discussion on the mailing list about Fiji vs. plain ImageJ1.x performance on multithreaded systems: http://imagej.1557.x6.nabble.com/very-very-very-slow-process-tp5020053p5020144.html
Any opinions/experience from the Fiji experts?

@imagejan I'm sorry, I don't have much insight into the problem, nor any time to investigate it. I agree with @axtimwalde that the parameters used to launch the JVM are paramount. I did not see any details from Michael Schmid about the exact invocations to java that were used. If I were to investigate I would definitely want to do the benchmarks after invoking java directly, rather than via the ImageJ launcher. The goal being to ensure we are comparing apples to apples.
The next step is then to profile the code to see where the bottlenecks are, comparing plain IJ1 with IJ2.
I will respond to the mail now with these suggestions.
