使用Minify来优化网站性能

Jun 13, 2016 am 11:13 AM
minify php5 yahoo optimization use application develop performance of website pass

Minify 是用PHP5开发的应用,通过遵循一些Yahoo的优化规则来提高网站的性能。它会合并多个CSS或者JavaScript文件,移除一些不必要的空格和注释,进行gzip压缩,并且会设置浏览器的缓存头。Minify 在设计上和Yahoo的 Combo Handler Service非常像,不过Minify可以合并任何你想要合并的JavaScript和CSS文件。

一般情况下,网站速度的瓶颈都在前端,而最关键的就是资源的加载速度,但是大多数浏览器都有单个域名并发请求数限制,所以如果一个页面中存在很多的资源,比如CSS和JavaScript文件,那么明显会降低网站的加载速度,比较好处理方式就是把多个文件通过一个请求来访问,这样既不会影响之前的文件维护,又会减少资源的清楚数量,Minify就是为之而生。

下面两幅图分别是启用Minify之前和启用Minify之后网站请求时间的一个对比,可以看出启用Minify之后,资源的加载时间从250ms减少到了125ms,总共节省了50%的时间。

C++ program optimization: time complexity reduction techniques C++ program optimization: time complexity reduction techniques Jun 01, 2024 am 11:19 AM

Time complexity measures the execution time of an algorithm relative to the size of the input. Tips for reducing the time complexity of C++ programs include: choosing appropriate containers (such as vector, list) to optimize data storage and management. Utilize efficient algorithms such as quick sort to reduce computation time. Eliminate multiple operations to reduce double counting. Use conditional branches to avoid unnecessary calculations. Optimize linear search by using faster algorithms such as binary search.
