But the cost of changing it was near to zero so in regarding
performance compared to work it goes towards infinity... :P
You never know before you try, otherwise it's just speculation. While
I was working on improving what jam prints it was a good change to try
out.
Anyway back on topic. I'd try most things that reduces build times, so
if we can do better than -O why not try it. It's an easy to revert
change.
Here's what gcc says: http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html
