Qubes Os4 very slowly comparing to Qubes 3.2

[frkl...@gmail.com]

Hi!

To start qubes os 4 takes a very long time comparing to Qubes os 3.2 (The double time or more) Is that normal? Also to start a new qube takes a lot of time. I realised also that the different qubes need more ram than before.

Is this only a behavior of my computer or is this in general?

I have an asus notebook i7 6500 u processor with 8gb ram and ssd

Thanks for the answers!

It does take longer than before in general because 4 uses HVM instead of
PV and because it has mitigations for Spectre/Meltdown which also slow it
down.

Could be my imagination but try **disabling Intel Speedstep in the BIOS-EFI



doesn't seem to help so much with boot time, lately, but seemed to help
with everything else.

that and maybe 8gb RAM is only going to get you a few VMs on top of the
defaults, and you can decrease the maximum Ram per VM, to get a few
more open, depending on what your doing in the VMs ..... but maybe you
knew that

That could be a good idea John!

I have only one problem. I can not disable Speedstep in the Bios- Uefi because there is no Speedstep configuration.

Does anyone know how to disable speedstep outside of the Bios at qubes os? I didn't find any solution.

disable c-states option if there is one. just make sure your pc doesn't run significantly hotter.

also as previous poster said 8 gb of ram is too small and 4.0 uses more resources then 3.2 as well. ssd also helps.

When intel first introduced power saving measures people always thought
that was the reason their computer was running slowly, but if frequency
scaling is working properly all it does is save you money on your power
bill - in your case it probably isn't functioning right and you should
investigate in dom0.

I use 8GB RAM and no swap without any issues, you can't run too many
VM's especially with resource consuming firefox but it isn't that terrible.

PVH should be just as fast as PV, I would investigate frequency scaling
and of course install the spectre microcode updates (very difficult
thanks to the good people at intel/amd not really releasing them)

this may seem silly, but try reinstalling. there was one RC of qubes-4 that was really slow for me. even after updating to the final one, it was still slow, but re installing the final one fixed it for me. still slower than 3.2, but only like half its speed instead of nearly unusable.

I also have some speed problems with the new Qubes OS.
In Qubes manager after any event I have to press "Refresh Qube list" in the top right corner.
Sometimes when qube is offline and I run command from Qubes manager it power on the qube but don't run the application.
Sometimes qube doesn't start at all and I have to press the "Refresh Qube list" and start it again.
Sometimes I get errors when using Qubes manager.
When it's unfreeze i see moving qube icons on the top right of the window.
If I start qube successfully and want to run command from the qube manager i have to press "Refresh Qube list" and then run the command, also qube right click options stay grey after start of the qube and have to refresh to show the new available menus.

Hope there will be updates or maybe I did something incorrect.(bios settings thru the installation, mistake in setup steps, unsupported laptop parts)

my machine is lenovo t460s with i5-6300u, 20gb ram, nvme ssd

My Qubes was running extremely slowly after updating the templates yesterday. I had to reboot system to fix it.
