Half of what? I'm not overly concerned about how long a prod build & deploy takes if it's automated. 10 minute build instead of 5 for 10% perf gain is probably worth it. Probably more and more worth it as you scale up because you only need to build it once then you can copy the binary to many machines where they all benefit.
