Hi Chris,

I posed your question to some folks in Compaq.  The resounding answer was
lack of page coloring in Linux.  There are some linker optimizations in
Tru64 UNIX, but page coloring was the most possible reason.

I was also told that Greg Lindahl and Joe Martin have posted patches to help
fix this.

Sorry I do not have a link right now.  I could find one if you cannot.

Hope this helps,
