So any one who can help me for fix this problem.

That’s good time if you boot from hdd drive. See systemd-analyze blame to see which services takes most time and disable if you don’t need something – forum search will be helpful with it.

Yes i have HDD and this is the systemd-analyze blame output :

So when i defrag my Manjaro partition this is the systemd-analyze output :

Startup finished in 6.441s (firmware) + 3.296s (loader) + 7.297s (kernel) + 29.155s (userspace) = 46.190s reached after 28.058s in userspace

Only one of the two memory channels is assigned.

Yeah i now but i want to know why 2 weeks ago the Manjaro kde boot up time is good and now it’s not

How old is the Manjaro installation ?

About 3 months
