Or does the forum know that TCC is running?
Try this. Start a new TCC v20. Watch it for a while in TaskMgr; I see a rock solid 0% CPU. Visit the forums and log in. Go back to TaskMgr. Now I see TCC bouncing around ... 0%, 1%, 2% (occasionally 5%) CPU.
Below are more quantitative comparisons. All three are newly-started TCCs. The first is idle for 5 minutes with no browser, the second is idle for 5 minutes while visiting the forum's front page, the third is idle for 5 minutes while visiting Google. Compare the CPU figures.
