It is possible to enable multicore for pacman?

I saw that while installations with pacman only one core is used. Is there an way to enable multicore for pacman with an line in the pacman.conf file?

I was able to enable multicore for AUR by editing MAKEFLAGS in cmake config file. It would be very nice if i should do it also with pacman.

What would be the purpose of that.
Multicore processing usually is applied, when parallel processing can speed things up.
Pacman basically does two main things:
1) Download packages.
2) Install packages.

In the first case the bottleneck is you network / internet bandwidth.
In the second case the bottleneck is the disk I/O speed.

In both cases multicore processing would not speed up anything.

Following @schard and to put it simply, files downloaded and installed via pacman are already compiled so you don't have to "make" anything, whereas AUR packages are not.

You can use powerpill to parallelize the downloads.
