[ace-users] ACE_String vs. std:string

No problem.

One is standard, and one isn't ;-)
The ACE_String_Base class was put in place for using strings when it
was not possible to portably use std::string (which may still be the
case) across all platforms that ACE runs on.

So, although std::string is standard, ACE_String_Base may be more
portable, depending on your target platform(s).

Neither offer any way to protect against multi-threaded access, if
that's your concern.

I don't have any performance numbers... The best bet here is to write
up a test that matches your intended use cases and measure them.

Best regards,
