In fairness, when sun spider was first released it did accurately reflect the core pain points in JS engines, as present on the web. That applied to V8 as well (though V8 introduced its own benchmark suite as well on release, it was overly focused on property access, and insufficiently on the parts of initial page load that sun spider just happened to cover). Of course all of that was _15 years ago_, no benchmark from back then is really reflective of anything useful, and they are largely no longer valuable for anything other than catching regressions.
