copy constructors hurting performance

[Shea Martin]

It's not so much STL as what the compiler does with ANY template.




You know you can just shut that off with a compiler option (-pto). Then it
does not share the instantiations of the templates between translation units.
Your program possibly gets a little fatter, as a result.

Thanks, I will try that. I posted about 6mos. ago, trying to figure that
out, and no one replied. I couldn't find anything other than a
description of SunWS_cache in HelpBook.

I just asked, they said no go. Don't want to change the standard
Makefile to include -pto! I give up. If I had known about -pto a year
ago when I started here, I would have used it from the start in my own
makefiles, and the the issue would probably never have arisen.

Thanks anyway.
