Matlab 2014b slow work and initialization time

I have been experiencing slow loading and initialization time after upgrading to Matlab 2014b under an academic license. I'm using a 64 bit win 7 computer and from my understanding it may have to do with the license type, having it being checked online every time the program starts.

It is almost impossible to work this way due to delays in running the simplest of functions after a 5 minutes waiting period it takes for it to finish initialization. Can someone recommend me a solution for this problem besides disconnecting the internet while working ?

Thanks in advance

I'm having similar problems, but my license is stand alone. My work is ~4x slower than with 2014a. Here's a simple benchmark:

2014a

>> tic; rand(10000); toc
Elapsed time is 0.939693 seconds.

2014b

>> tic; rand(10000); toc
Elapsed time is 4.373437 seconds.

I also noticed that 2014a ran at approximately the same slow speed as 2014b if 2014b was open at the same time.

Try getting a new computer. Here are my times:

>> tic; rand(10000); toc
Elapsed time is 0.870282 seconds.

Also don't just trust a time from a single first-time run of a function. Function caching and other factors can have a significant effect on function call time if you use a function multiple times e.g.

>> tic; rand(10000); toc
Elapsed time is 3.615152 seconds.
>> 
>> 
>> tic; rand(10000); toc
Elapsed time is 1.628210 seconds.
>> 
>> 
>> tic; rand(10000); toc
Elapsed time is 1.394690 seconds.

I am having the very same problem, also on an academic license. I have just upgraded to 2015a and i'm still having the same problem of slow initializing time > 8 minutes.
