Whenever you determine to use one tactic, it’s important to take into account the trade-offs and the way it might influence the opposite.
You possibly can apply compression for sources which might be massive, dynamic, or text-based, corresponding to HTML, JavaScript, or XML. On the similar time, keep away from compression for sources which might be static or binary-based, corresponding to pictures and movies. Additionally guarantee whenever you alter compression ranges, monitor efficiency and caching ranges and alter accordingly.
Get rid of redundant options and loops that waste vitality
Usually overview and refactor code to take away pointless options and optimize loops, notably throughout code opinions and efficiency optimization phases.
This method is crucial throughout all software program elements, specializing in ceaselessly used or resource-intensive sections, because it reduces CPU cycles and reminiscence utilization, resulting in decrease vitality consumption.
Whenever you do select to refactor code, nonetheless, it’s higher to optimize code solely when it’s mandatory and attempt to put in writing clear, maintainable code that’s straightforward to know and debug wherever and each time attainable.
