Hi Silvio,
Sidenote: SVN is not updated any more, latest version is on git:
https://gnunet.org/git/libmicrohttpd.git/tree/doc/examples/largepost.c
"512" is not recommended size, it's just suitable size for example.
Optimal value depends on OS, architecture, amount of available RAM.
You should experiment to find out what is optimal for you.
