本想提高开机速度的，可最后让我的开机速度更慢了...求解！

我打算提高开机速度，可通过各种方法，最后却让我的开机速度更慢了...
1、我改了 /etc/fstab 中的配置，如下（就最后一列数据）
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid                                       0 0
# / was on /dev/sda1 during installation
UUID=0912d7ca-2de8-4e45-b9fd-78af20f21bd0 / ext4 errors=remount-ro 0 0
# swap was on /dev/sda5 during installation
UUID=99294baa-a1d7-4683-a1e7-d68c88b35984 none swap sw 0 0

2、我通过chkconfig命令改了一些系统服务
linux@linux-desktop:~$ chkconfig --list

3、我把系统自带的游戏软件、打印机支持、蓝牙装备、自带brasero刻录软件等都卸了

本以为开机速度会更快。可最后开机速度慢了很多，况且有时也关不了机...
