Just to update that getting rid of the part of saving to the disk first, and getting rid of the defer as another person suggested, the number now are around 200ms for golang and 210 for erlang. IMHO it is not as huge as everybody makes it look like. Again, as you very correctly pointed out, this is of course only for IO intensive applications.
