I have installed Matlab R2016b on a new Windows 7 machine. Starting the desktop GUI is painfully slow, taking anywhere from two to almost ten minutes. The -timing flag creates reports similar to the following:

 total   item     gap      description
 =====================================
00   0.00    0.00   MATLAB script       
04   0.04    0.00   main                
51   0.42    0.05   LM Startup          
54   0.00    0.04   splash              
03   0.17    0.32      InitSunVM        
33   0.27    0.03      PostVMInit       
33   0.47    0.32     mljInit           
71  443.38    0.01     StartDesktop      
71  443.85    0.32   Java initialization 
72   0.00    0.01   psParser            
75   0.03    0.00   cachepath           
50   0.68    0.07     matlabpath        
00  120.29   444.71   Init Desktop        
23   0.00   123.73      SettingsConstruct
23   0.00   123.73     SettingsConstructo
50  124.75    0.00   matlabrc            
 =====================================

The startup time can be greatly improved with the nodesktop flag, forgoing the GUI in favor of a simple command window. Suddenly, the timing report looks more like this:

 total   item     gap      description
 =====================================
00   0.00    0.00   MATLAB script       
11   0.11    0.00   main                
62   0.46    0.06   LM Startup          
77   0.01    0.14   splash              
27   0.17    0.33      InitSunVM        
58   0.28    0.03      PostVMInit       
58   0.48    0.33     mljInit           
60   0.50    0.33   Java initialization 
62   0.00    0.02   psParser            
65   0.03    0.00   cachepath           
48   0.74    0.09     matlabpath        
43   0.00    5.96      SettingsConstruct
43   0.00    5.96     SettingsConstructo
72   7.07    0.00   matlabrc            
 =====================================
 Items shown account for 93.7% of total startup time [TIMER: 3 MHz]

Still not perfect, but good enough. Except for the fact that all the convenience features are gone. So, I run the desktop command. The profiler spits out over 100 seconds stuck in the MLDesktop.getInstance.initMainFrame(0, 1); line of the desktop function, the call to that Java method accounting for all the execution time.

How do I speed up the program's startup? Waiting several minutes to get something done is not acceptable.
