There are two main ways to parse Epub files, decompression and direct (relative name). Most books are read in decompression mode (including Ibooks on iOS platform). You can find the complete decompression document of the whole book in a certain location, but the disadvantage is that there is a certain requirement on the reading and writing speed of the cache location.
If the speed of decompression (including calculating and writing files) is slow, the speed of opening for the first time will be forced to slow down, plus rendering, typesetting and so on. And the time to open it for the first time will be long enough to drive you crazy; Of course, this also has advantages: the second opening speed will be faster than the direct opening, and it is also easier to realize technically. However, with the improvement of the built-in storage and performance of mobile phones, the problem of decompression will gradually become less obvious.
