The time of paper detection depends on many factors, including the type of detection system, the length and complexity of the paper, the congestion of the system and whether manual audit is needed. Generally speaking, most systems can complete the inspection within a few minutes to several hours, but it may take longer during the peak period.

For example, it may take a long time to check the copy of HowNet. If it is a school exam, it may be necessary to hand in the papers in a unified way, and wait for the school to unify the results. If the weight is checked in advance, the detection speed will be much faster, and the general detection time is 30-60 minutes. If it is submitted at night, the results will not come out until after 9: 00 the next morning. Size census and square inspection are usually faster. The detection time of an undergraduate thesis is usually around 10-30 minutes, and it may take about 30 minutes in the peak period.

Free weight checking such as paperfree and papertime can generally be completed in a few minutes, and the peak detection time may be longer. PaperFree is a similarity detection system for Chinese, English and multilingual papers. It has the functions of robot weight reduction and online weight change, which can automatically reduce the similarity rate of articles, detect while modifying in the same interface, and immediately feed back the duplicate checking results, so as to double the user experience and duplicate checking efficiency.
