e4rat
e4rat ("Ext4 - Reducing Access Times") is a toolset to
accelerate the boot process as well as application startups. e4rat
reduces disk access times through physical file reallocation. It is
based on the online defragmentation ioctl EXT4_IOC_MOVE_EXT from the
ext4 filesystem, which was introduced in Linux kernel
2.6.31. This utility leads to a high disk transfer rate.
e4rat has proven to be very useful for workstations
used by a single user using X windows.

Features include:
- e4rat-collect - gathers relevant files by monitoring file
accesses during an application startup
- e4rat-realloc - files are placed physically in a row on
disk. The reallocation of the files' content yields a higher disk
transfer rate which accelerates program start processes
- e4rat-preload - transfers files into memory in parallel to
program startup
