jdk8 build times

[Weijun Wang]

I have watched this thread for some time. Yes, SSD should be faster but 
Pete's build times are just incredibly slow and there must be some other 
reason.

I just open my Lenovo t410 (i5 2.6GHz, 8GB RAM, HDD) that has been 
asleep for the last two days, mkdir a new directory, run configure and 
"make langtools". The time spent is 00:01:05. Even in a VirtualBox guest 
inside my Mac Mini (HDD) with source and boot JDK all on the host, "make 
langtools" costs me 00:01:29.

And Pete's number (after disable Norton 360) is

     00:04:17 langtools

How can this ever happen?
