[SOLVED] e4rat No improvement can be done

Question

I'm not sure if this has to be posted in the Newbie Cornet, I hope it do.
Reading the post about e4rat in the forum and then reading the wiki about e4rat (https://wiki.archlinux.org/index.php/E4rat, I decided to test it. So I follow the steps in the wiki, and in the "e4rat-realloc" step, it just informed me: No improvement can be done .
It is possible e4rat can't help me? Or did I do something wrong?
What I do:
1.) put at the end of the line the init=/sbin/e4rat-collect
2.) reboot
3.) wait for the two minutes
4.) init 1 and then e4rat-realloc /var/lib/e4rat/startup.log
5.) here the message appeared, but still I continue with the procedure
6.) change e4rat-collect in the burg.cfg with init=/sbin/e4rat-preload
7.) reboot
8.) no changes in boot time
Things that maybe are important for this problem:
- line of burg.cfg about the kernel:
linux/boot/vmlinuz-3.0.3-ARCH root=/dev/disk/by-uuid/f168d4c1-ade6-4438-82ef-6edbfaa68c3c ootfstype=ext4 ro quiet add_efi_memmap rootdelay=5 resume=/dev/disk/by-uuid/68fa2501-b2ab-4125-a011-26cb0f20dbc0
    is vmlinuz-3.0.3-ARCH instead of vmlinuz-linux because is a compiled version by me
- line of modules at rc.conf:
MODULES=(acpi-cpufreq)
- line of daemos at rc.conf:
DAEMONS=(!hwclock ntpd @syslog-ng dbus wicd netfs @crond)
- I use mingetty instead of agetty in /etc/inittab (for autologin in console propose)
- I use .bash_profile to initialize openbox:
[[ -f ~/.bashrc ]] && . ~/.bashrc
if [[ -z $DISPLAY && ! -e /tmp/.X11-unix/X0 ]] && (( EUID )); then
exec xinit
fi
and that is all.
Thanks in advance for any help.

Answer 1

@diegoauyon
This is what I was talking about:
0 akai@Arch-Akai: ~ 8:37 ---> e4rat-realloc -h
Usage: e4rat-realloc [ option(s) ] [ mode ] files(s)
OPTIONS:
-V --version print version and exit
-h --help print help and exit
-v --verbose increment verbosity level
-q --quiet set verbose level to 0
-l --loglevel <number> set log level
-f --force force reallocating files
DEFRAGMENTATION MODES:
-p --use-prealloc Use pre-allocation kernel patch
-g --use-locality-group Create donor files in locality group.
Please avoid other filesystem activities.
-t --use-tld Take advantage of orlov's top-level direc-
tory spreading algorithm. This typically
leads to small holes between the files.
For me, using tld ( -t ) on e4rat-prealloc led after 2-4 iterations from 600 or so fragments to 20, what also seemed to do e4rat-preload more effective
