Android relies on Linux, so the main file systems include exFAT, F2FS, ext4 and so on. At the HUAWEI Mate 9 conference, Yu Chengdong introduced the EMUI 5 with F2FS instead of ext4, making it smooth. And this F2FS is SamsungDevelopmentIt optimizes 4K read-write for high speed flash memory.
EROFS is only in the early stage of development. The difference between the design goal and the existing read-only system is thatWith improved compression and dissemination, it saves space and improves performance and speed.
The engineer contrasted a set of LinuxThe serverAnd kylin 970 platform reads data continuously / randomly when using EROFS and EXT4 (ext4) two sets of file systems to perform compression operations, and the continuous reading of the server platform is not excellent.But random data has always had a distinct advantage over ext4, which is over 500%.
On the Android platform of Kirin 970, EROFS always takes a clear advantage in reading data in random and sequential way.
It is not yet clear when EROFS will be included in HUAWEI kernel by HUAWEI, not knowing it and HUAWEI.Is there any connection between the "scary technology" that has been heating up the mobile phone in recent days?
