Two more questions:
Are you building 32 or 64bit and how many jvm variants? I built 64bit so
only server.
What boot jdk are you using? 32 or 64bit? You haven't accidentally put a
debug build there or something? I'm using a 64bit jdk7u something,
probably 4 or 7, can't access the machine to check exactly today.

Besides removing Norton 360 I defragged my disk with Auslogics Disk

The disk is 500 mb and about half full.

Someone with a very similar laptop, T430 vs my T500, and a similar disk
does much better, by an hour. That disk has a 32 MB cache; mine has a
16 MB cache.

Maybe the disk has some sort of failure impacting performance (or the 16
MB cache makes a difference), though it does pass the PCDoctor/Lenovo
diagnostics. Also it is running in AHCI mode which apparently is
supposed to be better than using Compatibility mode

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?

The JDK source tree is excluded from virus scan.
The source has all the open and closed parts. I ran configure and "make
all" with all default parameters.

Nice to see improvement, but it's still far from where it should be.
For comparison, here are my build times on a similar, but probably
slower, laptop. Lenovo T410, i5 M 520 2.40GHz and 4GB ram, no ssd.
This laptop has no anti virus scanning installed.

A half hour improvement is nice, but looks like I need to switch to
an SSD.

Hi Peter,
try perfmon.exe to see where the bottleneck is. Most likely it is
memory or io. If you have the option, go for a SSD drive (you
will get
build times ~10 minutes).

Langtools taking 6 minutes is crazy long. Since there is no
