Second that. I would love to hear more about the hexloader. Is this a part
of the regular distribution or only pd-extended? Also, why is zexy not built
as a lib rather than being a collection of files? Does it have lower memory
footprint this way?
it's higher in several ways. Each additional dlopen() takes one filehandle
and each filehandle probably takes a lot more RAM than the machine code of
the average zexy class. Given dlopen() uses mmap() which loads the
*.pd_linux file content on-demand (in 4k blocks), one big *.pd_linux file
is more memory-efficient than one-class-per-file, even when using a low
number of different classes. On top of that, if your external takes 1k,
it's padded to 4k, and if it takes 4.001k, it's padded to 8k, etc.
however, if you loaded all of pd-extended as big libs, it would have a
greater virtual-memory-size than one-class-per-file, but that doesn't have
any advantage in practice.
