Is zen’s response time better?
There’s no magic involved then?

Of course, it should be better if you compile according to your cpu architecture😂

it depends on the tasks you perform on your machine, basically

Other than “performance”

zen ha no better performances, instead it has lower performances

If it’s meant for UI responsiveness, take a recording with both and count the frames

i don’t think you would see much difference if you don’t load your system otherwise. At least i personally (subjectively) don’t feel any differnce most of the time.
I think i see better responsiveness if i compile on all 16 threads, but the main reason i went for zen (and somehow stayed there ^^) was Futex2 when it wasn’t mainlined yet

Ah that’s a great setup right there lol

Not sure if it’d matter much 🙂

60% SQLite performance decrease on zen is pretty bad
il_muflone 2022-08-22 15:33:00
It has optimized settings for context switching, reducing throughput and increasing power consumption

Still a lot of people buy in that bs. I tried zen 3 times over the years, never staying in it more than a week

It really depends on your use case

Nah, what I see is a lot of confirmation bias =D

This is very vague.

Its just a waste of time

ston 2022-08-22 15:43:22
Better response time (preemption) usually means lower throughput performance

# 2022-08-22 15:43:21
Its just a waste of time

I would use lts kernel instead or even the stock kernel

# 2022-08-22 15:43:52
Just avoid it unless it has something specific to your work needs
il_muflone 2022-08-22 15:44:18
It may behave better under high load situations

# 2022-08-22 15:44:27
It “may”
grazzolini 2022-08-22 15:44:30
and how
# 2022-08-22 15:44:42
For me the high load situation barely comes
# 2022-08-22 15:45:01
I tried it once and it broke a lots of things for me, plus did not give nay performance output
ston 2022-08-22 15:45:08
Under high load the zen kernel may perform better for desktop applications, but of course the default is already very good

It gives the appearance of being more responsive, that’s true. But your system is still struggling behind the scenes. In the end, buy more RAM, more CPU. There’s no silver bullet

I tried it 2 months ago if anyone is curious when I tried it

Or you can use Wayland or window managers

Sure, the kernel doesn’t know what you want to obtain under stress. More responsivity for your UI, more priority for audio, more quickly to sync your data, more priority for an useless application you’re not immediately running

# 2022-08-22 15:45:48
Just switching from GNOME to KDE might make a massive difference

Yes
