Why should that be ridiculous or ignorant?
I stated that I was aware of the differences between interpreted and
compiled languages. But that does not change the fact that I believe
that this does not explain the performance gap. An execution time of
27.65 seconds against 0.33 seconds is not just nothing is it? It's a
factor of over 80 times. Besides, I implemented the same code in java
too, which isn't native code as well and runs in a virtual machine too,
and it executed in about the same time as c++.
