I likewise don’t see what Sebastien sees:
% /Users/Sage/sage-6.9.beta1/sage x.sage 
Time: CPU 0.85 s, Wall: 0.85 s
Time: CPU 0.65 s, Wall: 0.65 s
Time: CPU 7.47 s, Wall: 7.47 s
% sage x.sage 
Time: CPU 0.84 s, Wall: 0.84 s
Time: CPU 0.64 s, Wall: 0.64 s
Time: CPU 7.49 s, Wall: 7.49 s
% sage -version
SageMath Version 6.8, Release Date: 2015-07-26

This is on OS X, 10.10.4 (Quad-core Core i7 (2.6 GHz).
