Hi, I am experiencing big issues with Matlab startup. First Matlab(2009b) startup (right after booting) is very slow.
total item gap description
=====================================
0.00 0.00 0.00 MATLAB script
3.64 3.64 0.00 main
3.83 0.08 0.12 LM Startup

=====================================
Items shown account for 97.8% of total startup time [TIMER: 3 MHz]
version -java
ans =
Java 1.6.0_12-b04 with Sun Microsystems Inc. Java HotSpot™ Client VM mixed mode.
If I close and restart Matlab, then startup is much faster (mljInit takes 6.01 seconds)
It seems that there are something wrong with my java. I tried to update java, but nothing works.
I also tried methods on "http://www.mathworks.cn/support/solutions/en/data/1-2Z18MA/index.html" , but nothing works.
any ideas?

Kevin's tip works for my R2013b; I don't know why and how my R2013b booting changed from 2sec to 10sec. I definitely didn't change any system preferences.
But disabling "Automatically detect settings" absolutely helped.
Found a little trace on this issue, it's definitely has something to do with VPN software I have used (CyberGhost).
Thanks for sharing

I experienced the same. In fact I did some timings (with a watch), with "Automatically detect settings":
enabled disabled
2012a 11 s 4 s
2012b 10 s 6 s
2013a 7 s 4 s
2013b 9 s 5 s
(these are average of 2 or 3 starts, on a new laptop with an SSD drive and I7 processor)
