Actually seems like it doesn't...:
Using:
-O3 -march=corei7 -msse -msse2 -msse3 -msse4 -fipa-matrix-reorg -fwhole-program
made negligible (if any) difference running var-mt:
Original:
30.464
30.211
30.646
with g++ options:
30.381
30.487
30.277
However, using ICC 12.0.4 (-o3 -xssse3)
25.418
25.613
25.392
On the same machine (SB 2.2Ghz).
