At my past job, I wrote a pricing engine in C++, that with a Java front end
took an XML document of an order,
stuck the data in an OODB,
sent a message to the engine,
the engine did dynamic pricing of the order (utilizing rules expressed as C
expressions, which were interpreted at run time using a LR(0) C expression
parser I wrote)
wrote the data back to the OODB,
re-generated the XML order, with prices,
and sent it back.
It did all of that in under 400ms.
C++, Java and any other OO language doesn't have to be slow. Shoddy code
is shoddy code. Efficient code is efficient code.
