MATLAB: Simulink 2012a 64 bit is a slow starter. Can anyone explain me why

64-bitperformancer2012asimulinkslowstartupwindows 7

I recently moved from R2010a 32bit XP to 2012b 64bit W7. I got a much faster machine and more memory however… my Simulink takes as twice as before to start and I could not see any real advantaget on it. I neeed to execute some memory consuming task, like Matrixes calculations and such so there is where I would expect to get improvments. What I did not expect was to get a slower performance on Simulink model update.
Frankly, I don't know where the delay is coming from. Does anybody have a clue?

Hi all!
I found something that might interst you (I hope...). I ran a profiler on my script. It appears that the function that is taking all the time is this one:
 theInfo = internal.matlab.licensing.getFeatureInfo;
I haven't find much information on this function yet, but for what I understand from the name, it might be a function that checks with the server if you have the right to use the toolbox you want to use.
Could you run this line in your prompt please and tell me how long it takes to return the result (add "tic" and "toc" to get the computing time)? For me, it takes about 3 minutes to get the result. Way too long!
Regards.
