Hard to say without knowing more about what you did and what you observed. E.g. if your browser was an x64 build and your command-line V8 was an ia32 build, that would explain all sorts of differences. Telling us *which* tests exactly were faster in the browser would also add quite a bit of relevant information.
That said, V8 3.8 is ancient. I don't think anyone really cares about its performance any more. Please repeat your tests with the current development version (V8 trunk or bleeding_edge, Chromium M24 trunk or Chrome Dev channel).
