I also wonder if you have anything else unusual in your
test setup, such as a fast swap disk (mine is a partition
on the same rotating disk as source and target of the kernel build,
the default install for a RHEL6 system)?

I'm using a normal SATA HDD with two partitions, one for
swap and the other an ext3 filesystem with the kernel source.

Or have you disabled cleancache?

Yes, I _did_ disable cleancache.  I could see where having
cleancache enabled could explain the difference in results.

Or have you changed any sysfs parameters or
other kernel files?

No.

And are you using 512M of physical memory or relying on
kernel boot parameters to reduce visible memory

Limited with mem=512M boot parameter.

... and
if the latter have you confirmed with /proc/meminfo?

Yes, confirmed.
