# Julia needs work at "Benchmark Game": numbers seem off up to 100x slower, maybe "Julia AOT" entries needed?

I reordered by the cpu column (the last time column), to show more clearly, how these same languages/best implementations would rank if none of the entries where multi-threaded (or where we could be with, just that change, assuming linear speed-up), i.e. then we beat Ruby in the first benchmark…:

Go’s advantage is much less, about 100$ faster:

The low-hanging fruit seems to involve multi-threading.
