The length of paper duplicate checking mainly depends on the detection ability of duplicate checking system, the size of comparison database, the type and length of paper. The larger the comparison database of the duplicate checking system, the more data need to be compared when detecting the repetition rate of papers, and the longer the duplicate checking time will be; The efficiency of the paper duplicate checking system is also the key to affect the duplicate checking time. The stronger the ability to process these data, the shorter the time for duplicate checking. The type and length of paper also have an impact on the duplicate checking time. For some long papers, such as doctoral dissertations, due to more content to be tested, the duplicate checking time will be appropriately extended. There is no fixed time for paper duplicate checking, mainly depending on what duplicate checking system we choose.

It usually takes 20 minutes to check the whole article. However, the time of duplicate checking will also be affected by many factors, including the number of words in the paper, the system database, the number of duplicate checking people, and the time period for submitting the paper. If the number of words in a paper is relatively small, such as a paper with less than 5,000 words, the duplicate check may take less than 20 minutes, and it can be completed in ten minutes.

If it is a long graduation thesis with many words, it will often take more than 30 minutes to check the duplicate, especially for graduation thesis with tens of thousands or even hundreds of thousands of words, and the duplicate checking time may exceed 120 minutes. If a large number of people submit papers for paper duplicate checking, it has reached the upper limit of the paper duplicate checking system, which will inevitably affect the completion time of paper duplicate checking, and will automatically enter the sorting queue to wait for the duplicate checking detection of the system, thus delaying the time of paper duplicate checking.

The length of paper duplicate checking time is also closely related to the speed of paper duplicate checking. In fact, the speed of many paper duplicate checking systems is not much different, so the time gap of paper duplicate checking is not big. However, if there are many people submitting papers to the paper duplication checking system at the peak of paper duplication checking, the time for paper duplication checking will be much longer, and paper jam may occur. Therefore, in order to complete the duplicate checking of papers quickly, it is best to avoid submitting papers for testing at the peak of duplicate checking.
