Embodiment Construction

[0051]In the prior art, with the increasing popularity of dynamic webpages, the traditional method of measuring page loading performance by the time required to complete the entire page loading can no longer meet actual requirements. To this end, a method for measuring page loading performance through page stage time is also given. This method divides the entire page load into different stages and measures the loading time spent in each stage, where the start time of each stage is based on Determined by estimating the level of pixel change perceptible to the user.

[0052] After studying the above-mentioned prior art, the inventor of the present application analyzed the following: First, the method of measuring the page loading performance by the page stage time in the prior art does not give how to estimate the level of pixel change that the user can perceive, and lacks effective Secondly, it is not accurate enough to determine each loading stage in the page loading process b...

Abstract

The invention discloses a method and a device for testing a page perceived performance. The method comprises the steps of recording a load process of a page as N frames of screenshots according to a load time; calculating out a pixel change speed and an accelerated speed between each frame of the screenshots, and finding out accelerated speed discrete values which are beyond at least one standard deviation therefrom; taking each frame of the screenshots corresponding to the found accelerated speed discrete values as a key frame in the page load process; calculating out a speed for pixel change in a target area of each key frame, and finding out a first speed discrete value which is beyond the at least one standard deviation therefrom according to an order of the page load time; taking the frame of the screenshots corresponding to the first speed discrete value as a target key frame in all key frames; and determining the load time used from starting to load the page to loading the target key frame. According to the method and the device disclosed by the invention, the page perceived performance can be tested more accurately; and the true feeling of an ultimate user to a screen load reaction speed can be measured out.

Description

technical field [0001] The invention relates to the fields of page performance calculation, monitoring, analysis and optimization, in particular to a method and device for testing page perception performance. Background technique [0002] In today's web performance industry, one example metric for Page Load Time (PLT) is based on determining a start-render time and a finish-render time. Start Render Time in this PLT metric is defined as the time when a web page starts rendering something on the computer screen and Finish Render Time in this PLT metric is defined as when the web page finishes rendering on the computer screen The time for all content of a given web page. Another example PLT metric is called Time To Last Byte (TTLB), which refers to the average time between the first request being made and the last byte of server reply data received by the test tool . [0003] These example PLT metrics described above can be used in conjunction with many static web pages tha...
