看懂红字部分就明白了:它从你的启动时间里节省出了额外的几秒钟。这些节省来自于Alternative: e4rat-preload-lite
An alternative preload binary has been developed by jlindgren, it saves a few extra seconds from your boot time.
The savings come from
- * using pure C with no external library dependencies, which drops the number of linked .so files from 22 to 3
* preloading only the first 100 files (both inodes and file contents) before starting /sbin/init, then continuing to load the remaining files in parallel with the normal boot sequence.
