What does optimised mean?
Optimised means made or adjusted so that something works as effectively as possible. It is commonly applied to software, processes, systems, designs, and physical products, often suggesting that unnecessary complexity or inefficiency has been removed. For example, an optimised search function may return results more quickly, while an optimised manufacturing process may use fewer materials with no reduction in quality. The word also has a verb sense: to optimise something means to improve it through careful adjustment. In this sense, optimisation is not merely making something superficially more attractive but identifying and correcting weaknesses in order to achieve better results. The term generally carries a positive, practical connotation, though the implied comparison with an earlier or less efficient version can sometimes be understood as a criticism. The spelling optimised is standard in British and Commonwealth English, whereas American English normally uses optimized.

Optimised comes from the Latin optimus, meaning “best”—so optimisation is the art of making the best practical use of something.
