Hi,

I tried Jack's script and found a curious different performances for a 2 core processor when compared with a 4 core processor (and different builds). (The tests were not done in the same conditions, in Fedora there was a logged in user in GUI, in OpenSUSE only with ssh)

Attached is a screenshot of the results. The systems are (both with 4GB RAM):
On the left, Fedora Core 19 x64, Intel Core I5 2.5GHz (4 processors), gretl CVS 1.9.15
On the right OpenSUSE 13.1 x64, Intel Core 2 Duo 3GHz, gretl 1.9.14
On the other screenshot we have same OpenSUSE 13.1, gretl CVS 1.9.15

Also attached the config log results.

Chart Observation:
                     Fedora, 1.9.15cvs: peek 0.35 range 0 - 0.05
                     OpenSUSE, 1.9.15cvs: peek 0.08 range 0.02 - 0.08
                     OpenSUSE, 1.9.14: peek 0.10 range 0.02 - 0.09

It would be interesting if we have a stable benchmark script (I can even have it automated).
