I have a Dell Windows 7 computer with 4 cores.  According to Windows Task Manager Performance monitor, all four cores are utilized by ImageJ ImageJ 1.47 running on Java 1.6.0_12 with parallel threads set to 4.   The following operations used all four cores according to the task manager:

FFT bandpass filtering.
Median 7X7.
Math > Square root
Math > Square
Variance 5.
Threshold > convert to binary.
Analyze Particles...  (measured 24000+ particles)
Smooth
Remove outliers

I didn't try others.  If I can find a computer around here with more cores, I'll run the tests there too and post the answer.

Regards,

Michael

Without multi-threading, you will only get the benefit of increased RAM as compared to a typical current computer, unless the plugins use multi-threading.

Having said that, a plugin parallelizing calls to, say, StackReg, should also help taking advantage of multiple cores when you have a lot of images you need to process.

Ciao,
Johannes
