We have been doing battle with a number of performance issues as well as basic porting issues. Regardless of Studio 11 or 12 or 12u1 we see some odd behavior. My friend Giancarlo Niccolai explains one of these rather well at http://www.niccolai.cc/index.php?itemid=266
We have been fighting this battle inside the Blastwave build farm for a while and ultimately we had to look at what, really, was the compiler doing to result in such a massive performance drop? Well, see the above link please.

@Chandru. One way of trying OpenSolaris without the stress of repartitioning the disk is to run it in virtualbox (http://www.virtualbox.org/)
Instructions:
http://dlc.sun.com/osol/docs/content/IPS/virtualbox.html
The same page contains instructions for installing the 2008.05 release of OpenSolaris in a multi-boot environment. There are plenty of other pages which walk through the process (eg http://blogs.sun.com/amaguire/entry/opensolaris_windows_vista_dual_boot)

@Dennis. Very interesting blog entry. What's the quickest way for me to reproduce the issue?

Well, this (an exert of) the item class of which I speak in the post:
http://falconpastebin.appspot.com/39011
Just change pointer types in void* and int32/int64 into proper types, and check out the "<<<<" notes. Accessing multiple times the type inline (in writing) and using the copy() method, on a sparc32 machine (v8ultra), should do.
However, you may jump in #blastwave at irc.freenode.net, so other people there can help pointing out details that I may be missing.
