I am using Ubuntu 20.04. It seems like my system is running slower than it should.

When I turn on my laptop, it takes 1-2 minutes to boot.

The problem continues even after booting. Everything seems to be too slow, including the terminal, file manager and firefox.

Dell LATITUDE E7440 , intel core-i5 , 8GB RAM

Please help me review the output of:

systemd-analyze blame

htop command :

  • when I bought this laptop ,win 8.1 was installed on this .it was very faster than Ubuntu – Mohammad javad Aug 05 '20 at 17:55
  • take a look at htop or any other real-time system monitoring tool. You should review to see if there are any processes that are taking a huge percentage of memory, CPU, or disk r/w -- Report back with an edit to let us know what you've found. Please also include in your post the details of your hardware (especially what model CPU and the amount of installed RAM) – Nmath Aug 05 '20 at 19:05
  • what do you think about changing desktop ? in a Persian forum a person told me change to XFCE . – Mohammad javad Aug 05 '20 at 20:06
  • No, I would not recommend that you change your desktop unless you are very familiar with what exactly that entails. You could maybe try or install Xubuntu (official Ubuntu flavor with Xfce). As far as looking at htop you should review it when your system is "slow". This screenshot shows nothing consuming all your resources. And what about your CPU model and how much RAM do you have exactly? Maybe you are asking too much of your hardware? "Slow" is not a defined term. We need you to find some concrete evidence pointing to some culprit in your Ubuntu installation – Nmath Aug 05 '20 at 20:27

  • processor : Intel® Core™ i5-4310U CPU @ 2.00GHz × 4 --- memory : 7.7 GiB . First launch of each app is slow and it takes 54.982s to boot . on this laptop and win 8.1 ,boot takes less than 30s and launching apps was faster . – Mohammad javad Aug 06 '20 at 11:46
  • Well your CPU is a 7-year-old low-power laptop chip, so I would not expect it to be very fast to begin with. FYI: Windows 10 is probably using "fast startup" which is a hybrid suspend. That would mean it's not truly booting in 30s. You should also turn this off if you are dual-booting. Maybe you should not use GNOME, and use another flavor of Ubuntu like Lubuntu that is not nearly as bloated – Nmath Aug 06 '20 at 16:09
  • so there is no way to make it faster ? – Mohammad javad Aug 06 '20 at 17:22
  • We need to first determine the cause of the slowness. Have you been able to see any deficiencies as you are monitoring your system during the problem behavior? – Nmath Aug 06 '20 at 21:35
  • I didn't understand . but I monitored using htop and tried to open Telegram desktop ,it didn't open but in CPU usage NetworkManager go up to 10% ,some processes of Firefox using up to 5% . in Memory usage all tasks is for Firefox with 5.1% – Mohammad javad Aug 07 '20 at 08:08
  • Can you explain more precisely? I'm not good in English . – Mohammad javad Aug 07 '20 at 08:09
