Can't reply to the f2f's snarky comment.

I'm not saying I don't know how to change the value. I want to understand why the designers made the decision to do so.

Then read the three links pointing above?

All I see are a few perf graphs that show a 20% runtime reduction in a few cases and > 50% reduction in one case. This gives me no insight whatsoever what is going on under the hood.

Is it that for these dozen or so benchmarks, we end up using > 4K and < 8K of heap? So the extra 20% time is just going into a memory allocation?

P.S. Interesting that I got two snarky comments asking for a basic question about Go. Does not bode well.

stack, not heap. We are talking about changing the default stack size.

Yes and the book keeping overhead involved at the OS and runtime levels.
