For debug runtime performance, yes; for release runtime 
performance, no. Walter Bright made a pragmatic trade-off 
favoring fast compilation *and* fast execution generated machine 
code for the sake of rapid developer turnaround during the 
iteration loop. The primary objective of compiler-benchmark is to 
compare this developer inner loop—such as quick semantic checking 
and running unit tests in debug mode.
