MAP: 1.0255
DOLIST: 0.4794
DOSUBS: 0.4556

Interesting. For completeness, I tested also just doing {...} << \v/ >> TEVAL and got 0.4485 seconds.
So it's fair to say the overhead of using DOLIST or DOSUBS versus just applying the function to the list seems to be negligible (< 10 ms, probably uses some internal version of DOLIST).
MAP on the other hand is introducing a significant delay.

I also tested newRPL on this and there's a negligible difference between DOSUBS, DOLIST and MAP. Actually MAP seems slightly faster (< 20 ms with my calc locked to 6 MHz due to low battery). In fact, in newRPL doing MAP is even faster than applying the square root to the list directly (because it uses MAP internally, so it's MAP+overhead) but the difference in all cases is very small so as to be negligible.
