Browser client pauses for a few secs on each page action? Wha??

This might be specific to my browser, but I see it on several machines.

After each action I perform on my site as either a user or an admin, the browser freezes up for a second or two, preventing me from scrolling up or down, entering data, etc. Important to note that this happens after the page is fully loaded, not before or during. After a second then its all good again.

This could be, and here is your multiple choice question:

A. Something to do with my browser (Mac OSX, Safari) and other viewers don't experience this.

B. Some heavy resource module, like a statistics mod or something, is writing data somewhere and it would go away if I managed to turn it off.

C. My hosting company is slow and a difference service might avoid the issue.

I am not a rocket surgeon and I don't play one on television, but something leads me to B. Anyone have any other suggestions?
