Wise man say:

First rule of optimization: don't do it.

Second rule of optimization (for experts only): don't to it yet.


If you haven't profiled your code and have proof that MySQL++ is the 
source of your program's slowness, you're violating both rules.  If 
MySQL++ itself is not slowing your program down appreciably, then you 
have no hope of speeding it up by changing MySQL++.
