Does the mainstack have a default button?  Those throbbing buttons eat 
cycles like crazy.  Even Apple's NavServices dialog will cause an app to 
go to 7-10%, but in Rev it's higher because of the greater flexibility 
offered (it has to buffer the image to allow any backdrop behind it, not 
just the OS stripes).

But even with the extra work Rev is doing, on my system it never takes 
more than 25%.  Are there pending messages or other background tasks 
which may contribute to this?

Also, which version are you using?  In older versions a high spike for 
the throbbing default button was more common, but this was reduced 
dramatically  in v2.5
