Load time is how long it takes for a webpage to be loaded and usable by a browser. Often in web page delivery a page is compressed in the Gzip format to make the size of the download smaller. This practice prevents the first byte from being sent until the compression is complete and ...

在前端开发领域中,time to first byte(TTFB)指标是指浏览器发出请求后,服务器第一次返回数据所花费的时间,即从请求发送到收到第一个字节的时间。这个时间包括了浏览器发出请求到服务器接收到请求、处理请求并返回响应的时间。 TTFB 是一个重要的性能指标,因为它直接影响到用户的体验。较长的 TTFB 会导致用户在等...
例如,Time to First Byte也称为首字节时间(TTFB),就是衡量用户的浏览器从你的网站服务器接收第一个 "字节 "的数据所需的时间。不是渲染它或在屏幕上显示它,而是简单地返回一个字节给浏览器。 在这篇文章中,搬主题将解释什么是TTFB以及为什么它很重要。然后我们将讨论如何衡量它,以及你如何在你的WordPress网站上...
如果你想优化你的网站的速度和性能,重要的是知道要注意哪些关键指标。例如,Time to First Byte也称为首字节时间(TTFB),就是衡量用户的浏览器从你的网站服务器接收第一个 "字节 "的数据所需的时间。不是渲染它或在屏幕上显示它,而是简单地返回一个字节给浏览器。
当TTFB（Time to First Byte）超过500毫秒时，用户会明显感受到白屏。
Actual vs. perceived time to first byte. Three key factors determine TTFB:network latency, server load time and server processing time (dynamic HTML content taking longer to process than static pages). Web page load times—and especially TTFB—have been shown to be more prominent SEO ranking fa...
First byte time represents the server delay – how long the server needs to process the request, including database access, calculations and generating the response. High first byte time may indicate high server load, inefficient database queries, calls to busy external resources like Google or Fa...
Time to first byte Time to receive headers Time to load the HTML of the site If you would prefer a response time recorded as TTFB, then you can use a ping check. Fast and Reliable Website Monitoring Make sure you’re always the first to know when your site is unavailable or slow. ...
Every HTTP request that receives a response has a Time to First Byte. When talking about requests after the initial document request, TTFB usually only refers to the time spent waiting for a response to the HTTP request. For example, you can see the per-request TTFB inWebPageTest. Here it...
