Um. Wrong word, I apologize. I meant discontent. English is not my
mother's tongue.

You are deliberately misinterpreting my words.

Henning, take a deep breath please. What theories?

I said earlier that I will not use Fleece unless ultimately pressed
to, no matter however fast it would be, and that I trust your claim
that it is as fast as it is advertised.

I want to try beating Fleece with LJ2 (and I said that I'll have a
time for this not earlier than later this week). Even if I (or any one
else) would not beat it, not 10x performance, nor 100x performance
gains in JSON serialization would pay for the potential maintenance
costs increase, incurred by inclusion of your library into my
production code.

I'm not debating the speed. I'm debating the engineering approach.

Regarding my actual points your very README file proves all that is
needed to prove:

-------

Part of Fleece' speed advantage over other JSON packages is derived
from the fact that it *accesses the Lua table data at the core C
level, below the Lua C API*, which frees a significant number of
cycles.

<...>

Fleece can power up *inline assembler* to make the string escaping
sufficiently fast.

-------

Emphasis is mine.

The whole debate is about above two points, not about the speed.

Let's not get personal.

And lets either tone down, or move to other public list — Lua-L is not
a place for such heated debate.
