Optimization can reduce readability and add code that is used only to improve the performance. This may complicate programs or systems, making them harder to maintain and debug. As a result, optimization or performance tuning is often performed at the end of the development stage. Donald Knuth made the following two statements on optimization:
The use of optimization software requires that the function f is defined in a suitable programming language and connected at compilation or run time to the optimization software. The optimization software will deliver input values in A , the software module realizing f will deliver the computed value f ( x ) and, in some cases, additional ...

Making files contiguous so that they can be read without unnecessary seeking. In Windows 2000 and later operating systems, Microsoft Drive Optimizer has the following limitations: It does not defragment files residing in the Recycle Bin or files that are in use. [7] In particular, this includes the registry, page file and hibernation file.
Excel's storage of numbers in binary format also affects its accuracy. [3] To illustrate, the lower figure tabulates the simple addition 1 + x − 1 for several values of x. All the values of x begin at the 15 th decimal, so Excel must take them into account. Before calculating the sum 1 + x, Excel first approximates x as a binary number
