The Whetstone benchmark is a benchmark for evaluating the performance of computers.
According to Whetstone, you can see below the number of MWIPS (Million Instructions per second) for java and C++ applications in an Intel core 2 duo 1.8 GHz machine.
Java = Around 1000 MWIPS.
C++ = Around 1600 MWIPS.
If your application is slow who else can you blame now? Definitely your algorithms!!! Revamp all your old slow paced code.
Let your application top the throttle ... Speed up ... drhhhh
