I tested the read speed of the hard disk with the command sudo hdparm -Tt /dev/sda. And received

Timing cached reads:   20390 MB in  2.00 seconds = 10204.16 MB/sec
 Timing buffered disk reads: 332 MB in  3.01 seconds = 110.37 MB/sec

. The system boots in 2 minutes without grab. How can I increase the system boot speed? I use arch linux kde 5 shell. 1 gb hangs in RAM after loading.

See what slows down when loading. I have even on the atom - loading 3-4 seconds, without graphics - Ubuntu. With graphics, seconds are 3-5 slower.
Most likely, some service is slowing down, or incorrectly configured DNS servers, which affects all network services.

Put the system to sleep instead of shutting it down completely.

And from there, take a look at the " Systemd " link.
