I find that simply having the Fearless Forecaster Board open is driving CPU Utilization to about 50%. That is board open, not doing anything. That is a lot of CPU to do nothing.
And what evidence do you have that proves that this board is the cause of that CPU Utilization? Of course the impact on CPU Utlization will depend on the power of the CPU in the first place, but on my machine I see no change in utlization if I tab in and out of having the board loaded.
FWIW, my CPU utilization is about 15% right now. That's with 3 TT browser windows open, plus my quote system, plus my email, plus 30 windows in Firefox (I know, I have a disease) plus a few spreadsheets.
Frankly, I think the board is running muchmore efficiently, at least for me. Your browser and mileage may vary...
