That's not true. Yes, -Os stands for size. However code size
_can_
translate to performance increase. Think about cache footprint, etc.
Smaller code means more can fit in the cache. It also results in a
smaller DRAM footprint for thinks like shared libraries, etc.
Smaller binaries means less IO, less chance of a cache miss - there are
advantages to trying it. Someone actually did a comprehensive test using
FCt1 once, I'll see if I can't dig up the PDF, it had some very good
metrics we could look to duplicate.
