Hello everyone!
I have noticed that my laptop booting is slow, then I read the wiki and google around but there seems no answer for me.
It seems that this all because of the NetworkManager, so I post it here.
This is my basic information:

hello

Thanks a lot! I'll try.
Update:
This really did a great job!
4.683s NetworkManager.service
2.680s libvirtd.service
2.305s accounts-daemon.service
1.238s alsa-restore.service
But I wonder whether there's some improvement?
Update:
Ok, seems there's no better answer, but I think this enough for me. Mark it SOLVED
I delete the journal files and
sudo vim /etc/systemd/journald.conf
uncomment SystemMaxUse=
let it equals 50M (depends on you)

But I wonder whether there's some improvement?
Do you mean why there's an improvement after removing the journal files?
first of all, I hope that you know what systemd journal is, and what files you just deleted.
systemd journal stores all system logs in database files in /var/log/journal/
every time you boot up your system, journald will log the entire boot process and stores in its database (and continue logging of course).
over time the journal will get huge (unless you limit its size) and fragmented, which could slow down reading and writing from the it greatly.
so, if writing the log during the boot process slows down greatly, it will certainly have an detrimental effect on overall boot speed.
I hope that makes sense :)
I think I saw this mentioned on some systemd TODO list, so developers should aware of this and possibly trying to figure out some workaround.
In the meantime limiting journal size is probably a good idea.
If you happened to be using btrfs, disabling COW for files in /var/log/journal and 'autodefrag' mount option may also help some.
also defragmenting the files in /var/log/journal if your file system supports it

First of all, thanks to your very clear explanation!
English is not my mother tongue, so I think I express me in a wrong way.Sorry for this!
What I exactly want to mean is that is it possible to make booting more faster?

No worries, I'm not native speaker either, so I can certainly understand :)

Unfortunately there's no simple answer, but probably yes.
Basically it comes down to figuring out what's slowing down your system bootup, and working around or fixing those issues if possible.
If NetworkManager is slowing you down, possible workaround could be changing its .service file to make it start on background.
I described how to do that here. Note that there could be issues if some of your startup services require network connection.
Also, check out Improve boot performance wiki article for some tips if you haven't already.
Installing linux-ck from graysky's repo or AUR might be beneficial for boot speed as well as your system's overall performance, by enabling BFQ io-scheduler and Brain Fuck Scheduler.
Both are experimental, but should work quite stably, especially now as certain long standing bug was just fixed in BFS.

I have searched your tips, yes, they are all complex method almost.
I'm afraid to make my arch dead , so I think I'll stop here.
Thanks a lot, again.
