You might want to give the official release a try. (In other words,
I don't think it's safe to use our "distribution" to judge EKOPath.)

AFAIU, LNO is not performed at -O2, so you should use -O3.
And, if I managed to build the IPA module, you should use -Ofast.

If you are interested, I can run SPECint2000 on a 3.0 GHz Northwood
core, and report the results here.

Finally, as James noted, the performance on AMD CPUs should be
higher than that on Intel CPUs.
