This comment by mdm@chromium.org makes me think there's a puzzle to be solved here:

The teleportation rate is actually a linear function of the number of tabs you have open. Each tab has to teleport a certain number of goats to operate, although as dank points out we were able to optimize it during the Linux port and reduce the number of goats required. I have some further optimizations in mind if we'd like to reduce it more to address the issue mentioned in comment #11.

Without looking at the code, what could that column really be measuring?
