readahead-fedora

Fedora's implementation of readahead to preload boot process files

Variants:
"readahead" is the term used to refer to a tool that preloads files in this case used during the boot process to make the system boot faster.

This implementation of the tool provides the following features: * It can take multiple lists of files to be preloaded, and sort them according to their position on the disk. * It preloads the inode tables on ext2-based file systems. * It opens the files without making the system update their access time, therefore avoiding extra disk writes. * It uses a lightweight monitoring daemon.

INTRODUCTION
------------

readahead reads a list of files in advance and adds the pages to the page
cache.  The files are accessed and read in an efficient manner to minimize
disk seeks.  Best performance is achieved on an ext2 or ext3 file system.

The program works in three modes:

1) full mode

	readahead  /etc/readahead.d/*.early

   The program will read a new-line separated list of files f

Fair comparison of bootcharts
-----------------------------

When comparing bootcharts of different readahead implementations an
extra consideration should be taken.  readahead-fedora also preloads
files that are used after the end of the rc2, which might affect the
results of a bootchart if the bootcharting program is stopped at the
end of rc2.

In order to fairly compare bootcharts the READAHEAD

 Readahead lists naming convention
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 {early,later}.sorted

	The sorted lists are used for "fast mode" and this kind of lists has
	the greater priority for boot scripts. These lists are generated from
	custom.{early,later} or *.{early,later} lists by (for example):

		readahead  --sort --output=early.sorted foo.early


 custom.{early,later}
