I'm sorry, but you are not providing enough information to give any  
useful comments. There is no reason why a generic library would error  
out because certain code is "too slow". Is this a real time  
application on an embedded system or so?

If your program depends on converting floating point numbers to  
string representation as quickly as possible, I agree that FPC is not  
the tool you want in this case.
