Why Manjaro appears to be much slower than Ubuntu on my system?


Before this fresh installation of Manjaro Plasma, I had dual-booted Manjaro xfce alongside Ubuntu Gnome on my SSD hard drive. Despite all I’ve heard about the low performance of Gnome DE, It was a lot better than Manjaro xfce!

Now a day past after the fresh installation of Manjaro Plasma instead of that dual-boot and I’m already exhausted by how slow it is.

  • Could it be because of the graphic driver misfunction on Manjaro?

  • Why is it like so?

/dev/nvme0n1 is SSD and /dev/sda is HDD.

The bootloader is UEFI

Ubuntu often performs its own optimizations on its kernels. Also mostly don’t leave the gnome original.

Otherwise, I rather think that the difference in speed comes from the respective desktop.

And I have found the opposite: Manjaro being faster, more snappy than Ubuntu.

So I’m guessing it’s subjective.


DITTO completely agree


Is Manjaro KDE installed to the partition on the Seagate 2.5" 5400rpm hard drive ?

Please post more information about system including GPU driver

inxi -Fazy
4295MB  linux-swap(v1)        swap, legacy_boot

Not the reason for slow performance but an odd swap setup for a 16GB ram machine. What does the legacy_boot flag bring on an uefi machine with gpt drives?

I didn’t set this. I even reinstalled the manjaro to fix it but it didn’t show anywhere.
It’s probably because of this problem and I wonder if it’s actually the reason of low performance.

This is the manual partitioning summary. Does it relate to the repeat of the format and set file system part of the linuxswap?

No it’s installed on the Samsung

Note that I’m running the commands on the Manjaro Gnome live boot

Also I think it is worth the mention that in live boot the performance is great

Well, who did, then?

I don’t see the mention of swap, legacy_boot anywhere in the manual partitioning summary! I guessed that it might have been because of this problem

Just post the whole damn inxi geeze.

in live boot the performance is great

If there is no performance issue when system is booted from Live ISO, system data from Live ISO is not helpful for diagnosing alleged problem with installed OS
