As fas as I can tell, yes.

I am more interested to compare times rather than get the lowest possible
number.
Except the extra checking which was added by the Dataflow merge is
known to be slow which is why you see the jump. This jump is not seen
with --enable-checking=release which is the default for official
releases of GCC.
