[PC-BSD Testing] FF3.5.2 runs slower on PCBSD than Windows?

I had run Geekbench before, and here are the results (I had FF3 running in two windows with multiple tabs, Krusader, and a doc open in OO).  Not sure how accurate the results are since it's running as a Linux process.  Note it incorrectly reports the OS as 32 bit and shows RAM of 2GB when I actually have 6GB, and some other system number don't look right either.

---------------------
I closed down all other apps and reran the test and it was, uh... lower: 3400.  So not sure what credibility it has.

The Geekbench browser reports an average score for this processor running on Windows of 7500.  Is PCBSD 64 bit not taking advantage of the multi-core processor or is this because of the Linux compat layer?

Again, I don't think I'm comparing apples to apples here. 
 I suggested making some of these benchmark suites into PBIs, but nothing's happened yet.  Also tried running the Phoronix test suite, but couldn't get it to run.

Have you tried installing geekbench with runports? I can provide some performance metrics to compare against my system:AMD Athlon X2 5000+ BE @ 2.9GHz4GB RAM2x 7200RPM 320GB WD RAID 0Asus M2N-E
GeForce 7600GTPC-BSD 7.1.1 - AMD64

I built what should have been a kick-ass system with:


Intel i7-920
6GB RAM
RAID-0 7200RPM drives 
Asus  P6T Motherboard - (Intel on-board RAID)
Radeon HD-4250 VGA
PCBSD 64Bit

But in various benchmarks it comes up short every time.

I just ran this browser test and I scored 1296 pts using FF3.5.2 VS double that running on Windows ??  It's not clear what OS the average results came from, but I presume it was Vista.


My benchmark results breakdown:



	
		Rendering - 1247
		
	

	
		Social networking - 1833
		
		
		
	

	
		Complex graphics - 3134
		
		
		
	

	
		Data - 1714
		
		
		
	

	
		DOM operations - 1264
		
		
		
	

	
		Text parsing - 741
		
		

		
	

I did some other OS benchmarks too recently, and was similarly underwhelmed.  Anyone have a clue why?  Anyone else done any benchmarking?

This machine is sucking up 175 Watts in electricity and I don't appear to be getting my money's worth.  Bumming...
