I’ve found this blog post while crawling the internet for solutions to MATLAB R2009A’s abysmal GUI performance under OSX 10.5.7 (and 10.5.6). Aside from the poor “bench” performance that is well documented on the internet, I am wondering if you have any advice on how to enable MATLAB to use Quartz instead of Java.

I tried your code to check if MATLAB is using Quartz and get “false” as a return.

I have tried the method suggested here:

http://www.macosxhints.com/article.php?story=2007112503413229

And found that R2009a already comes with the ‘java.opts’ file with the line of code that is supposed to enable Quartz. However no matter what I do with the file (removing the comments, placing the file in the other locations suggested by the website, etc), I cannot get MATLAB to use Quartz, as I still get a “False” response.

There is also the perceptual difference in using software that feels like it is running on a sub-1 Ghz computer (the quarter to half second that it takes for Matlab to confirm “a=3″, and the molasses like scrolling experienced in M-files.

Do you have suggestions on how to enable Quartz on MATLAB R2009A under OS X running a Mac Pro? I have been able to get Quartz running under R2008B on a Macbook Pro…

Note I have ensured Matlab is using Quartz (typing " java.lang.System.getProperty('apple.awt.graphics.UseQuartz')" at the matlab commandline should return true), and also tested with 2008a and 2008b. What is interesting is that OpenGL performance itself is faster in OS X than XP independent of Matlab for me. Something about XWindows causes Matlab to turn to treacle in drawing speed. Again, returning to GUIDE, I always ensure the same font is available on both platforms, and try to follow the cross-platform guidelines but GUIDE still causes clipping issues for UI widgets on OS X.

The preceding release, R2008a, behaves in a similar way; and the pre-release R2009a does not seem to be significantly faster. The results I quoted are for release R2008b.

Are you using a pre-release version? Mike Giovanni,

What version of MATLAB are you comparing with? Are you using a pre-release version?

I would be curious to know what the difference in speed depends on (especially but not only in the case that it cannot be modified by much). But maybe this is a question for the Matlab newsgroup rather than for this blog. G. Thanks for that.

I have also tried the bench command both on OS X and on Windows XP (same computer, same version of Matlab, XP running with bootcamp) and on OS X FFT is 1.7 times slower, ODE is 1.9 times slower, Sparse is 1.3 times slower, 2-D is 2.6 times slower and 3-D 1.4 times slower; LU is approximately equal. I have read of similar results from other people. For what regards the performance of Matlab on OS X, there is difference in all parts of the “bench” test except LU decomposition.

There are many other developers here at The MathWorks working to make this a reality. The performance issues you mention...are you referencing actual computational speed, figure drawing speed or user interface feel? I've forwarded your comment/request regarding GUIDE on to the appropriate team. Thanks for the feedback Ian, -Ken Hi Ian,
