Matlabpool very slow to open workers

Question

I have just put together a new rig (i7-4770K, 512gb SSD, 16gb DDR3 2133 mhz ram), and installed MATLAB r2013a. When I invoke the matlabpool command it takes an extremely long time to open up each individual worker (the ones you see open in task manager). On my old rig it was about 10 seconds, but my new one takes 1 minute. I have tried with just 1 additional worker and it takes a long time.

Any help would be appreciated.

Thanks

You can try executing the following to eliminate one of the newer features (included in versions after MATLAB R2012a) that has caused some people (including myself) problems:

distcomp.feature( 'LocalUseMpiexec', false )

Mathworks made some changes to the way the local scheduler launches the workers for R2010a, that change reverts it back to R2009b.
