No, this is not true. Strong static typing and other compile-time information can (at least theoretically) allow improving both security and performance.

For example, look at single address space operating systems. Switching between security domains is cheaper when you don't have to switch address spaces. That's an improvement to security that allows increased efficiency.

We were talking about C code. That doesn't have strong, static typing with built-in safety. C developers also rejected things like Cyclone and Clay. So, my comment assumes a C-based platform (esp OS).
