Hi Gary,
Well, my only concern here is to pick the best optimization for my
system in the fldigi configure script. If I'm reading the document you
linked correctly, the "native" choice will have the compiler make
optimization choices based on the CPU of the system it's running on.
Which for me seems like a good choice!
I think my takeaway is that unless you are compiling for a different CPU
than what you are building on, the "native" choice would always be the
one to use.
Thanks,

This is a big-ole can of worms and the opinions range from mild to wild :-)

There are many, and it's mind boggling when you look at all of them, but
for most uses, a few can have dramatic affect.

Post by Bob Snyder bob.snyder-***@public.gmane.org [linuxham]When building fldigi, the configure script gives several options for
*--enable-optimizations use x86 optimizations
(none|sse|sse2|sse3|native)*
What is "native" and is it likely to add much performance? Is it
preferred to sse3?
Thanks,
