Strictly speaking, this is off topic and should be asked somewhere like here forums.linuxmint.com –  Chris Carter Feb 24 '13 at 11:13

That argument has been used before. The fact remains that some modifications are made. –  user25656 Feb 24 '13 at 11:52
    
The only thing where you can -see- a faster boot: change the disc to an SSD –  Rinzwind Feb 24 '13 at 14:10

Seeing the bootchart questions:

  • kthread and similar stuff is not KDE but kernel related and unavoidable.
  • ureadahead is supposed to speed up application start on the cost of a longer boot time.
  • upstart-udev-br bridges udev events into upstart and is required for hot plugging.
  • upstart-socket, dbus and polkit are desktop comfort and security related.
  • modem-manager to dhclient depend on network speed.

General recommendations:

  • Don't mount NTFS volumes during startup; add noauto to partitions that you use rarely.
  • If you don't use WLAN or bluetooth, activate the killswitch or disable it by network-manager.
  • Remove unused printer drivers; If you rarely ever print, disable the cups service.
  • Gnome / Unity can be somewhat hefty on older laptops. Explore alternative desktops like xfce or lxde.
  • Consider buying an SSD. That really speeds things up.

A lot of the startup apps are now hidden.

Open a terminal and type:

sudo sed -i "s/NoDisplay=true/NoDisplay=false/g" /etc/xdg/autostart/*.desktop

Open startup applications:

NOTE: Don't uncheck/disable what you don't know.

Are you sure? I think will make them be not hidden just from startup applications menu, am I right? –  Mostafa Shahverdy Feb 24 '13 at 10:59
    
Yes. All apps are now listed. –  Alex Seicean Feb 24 '13 at 11:01
    
But ok, witch ones should I remove? –  Mostafa Shahverdy Feb 24 '13 at 11:03
    
That depends on Your specific needs. I personally found out that disableing the startup apps didn't speed up my boot time. –  Alex Seicean Feb 24 '13 at 11:05
