β2 is extremely processor hungry

Just for what it's worth before things are optimized.  I've noted that Beta2 is extremely needy of my processor on a regular basis. 

The graphic below is a 60 second snapshot showing overall processor usage.  The orange line is Logos 4.

I have two observations you should notice. 

1. I have a dual core processor so when Logos shows 50% that means that it's using 100% of one of the cores.
2. Notice that every second or two Logos demands a surge in processor usage. 

You should know that I'm not doing anything when this snapshot was taken.  This is 60 seconds of just sitting completely still with no input from mouse or keyboard or anything. 

A list of my running programs might help for comparison. 

• Bibleworks 8
• Logos 4
• Firefox (two tabs (a new low for me !))
• Notepad
• Openoffice.org writer
• Resource monitor
• Digsby (instant messenger platform)
