Can you be more specific as of what is slow and how to reproduce it?
There was a report that the console UI gets slower in Sierra as the length of
the output increases - you can clear the console to avoid that, but the cause
is so far unknown, likely related to Xcode 8.3 an Sierra interaction since the
problem has not appeared in Mavericks builds for R (try using R 3.3.3 to see if
you see the same problem).

I have not seen that error, is it reproducible?
