Ticket #3834 (new defect)
OpenSolaris guest has high system time overhead

We created an image using OpenSolaris 2008.11 (32-bit), MySQL, OpenDS, Glassfish to support applications. After the image boots, the apps have started and "steady state" is reached, the image has 30-35% system time constantly being consumed. We've seen this on vbox 2.0.x, 2.1.x, and 2.2.x.
We've seen this happen on the following Host OS platforms: OpenSolaris on Sun Ultra40 (AMD) Mac OS X on MacBookPro (Intel) Linux (Ubuntu 8.10) on Toshiba Laptop (Intel) Windows XP on Acer Laptop (AMD)
I "profiled the kernel" using a dtrace script and the kernel is calling: unixtsc_read / genunixgethrtime_unscaled A LOT.
I'll attach the output of the script and the dtrace script
