Every time I plot something it takes several seconds for MATLAB do draw it. Specifically:
>> figure
opens a figure with no significant delay but
>> plot(1:10)
takes about 10 seconds before anything is drawn.
Any ideas what might be wrong? I've attached a file with my DxDiag information below if you want to know what my setup is. I'm currently using MATLAB R2016b but I had the same problem with R2014b.

Which renderer do you use? Does the profile r reveal, where the time is spent?

For certain graphic cards these performance issues can be resolved by using the software implementation of OpenGL. You can switch to this implementation by executing the command given below at MATLAB Command Window:
>>opengl software
To permanently use OpenGL software, execute this:
>>opengl(save,'software')

Elizabeth Hearn: which release of MATLAB are you using, and which OS-X or MacOS release?

Just a little mistake: for me it worked
opengl('save','software');
with save between quotes
