Summary: e4rat is a toolset to accelerate the boot process as well as application startups
Description:
e4rat ("Ext4 - Reducing Access Times") is a toolset to accelerate the boot process as well as application startups. Through physical file realloction e4rat eliminates both seek times and rotational delays. This leads to a high disk transfer rate. Placing files on disk in a sequentially ordered way allows to efficiently read-ahead files in parallel to the program startup. The combination of sequentially reading and a high cache hit rate may reduce the boot time by a factor of three, as the example below shows. e4rat is based on the online defragmentation ioctl EXT4_IOC_MOVE_EXT from the Ext4 filesystem, which was introduced in Linux Kernel 2.6.31. Other filesystem types and/or earlier versions of extended filesystems are not supported.
