When a program is comprehensible, you can assess its performance. A tangled control flow makes a program difficult to understand and maintain, and inhibits the optimization of its code.
To improve the performance of your program, examine at least these aspects:
You can write programs that result in better generated code sequences and use system services more efficiently. These additional aspects can affect performance:
