No, I wasn't seriously trying to compare the timings as denoted by the prefix; 'I can't compare machines etc'.
It was simply an observation that there has been work on the Opera engine subsequent to 10.60, and that your prior statement regarding performance improvements might have been erroneous.
Um.. not true:
They've updated the engine in the latest release.
I can't compare machines etc, but at least on my copy of Opera 10.70 the execution time is: 15145.0ms
A touch faster than Firefox Nightly no?
But I agree with the other comments, this is just a JS benchmark, I'd rather get a feel for memory consumption and page render times these days.
