What i am saying is that as long you try to "improve" your project with marginal "improvements" you will fail at anything. For the majority, things like message pack is micromanagement. It will cause a lot of work and noise with minor improvements. The tradeoff is too high, for the majority. The minority are people who already have shit done. That are people who are actually saving alot of money with squezing the last bits of performance out of something. my viewpoint is probably out of scope because its wholistic, but thats where to start.
