Check CPU Usage

dino

rosenrot not yet, but will try to have some update soon.

Leirk

Summary:
I am experiencing frequent browser freezing and high CPU usage, which forces me to forcefully quit the browser, resulting in the loss of important tabs. Due to the unpredictable nature of the issue, I am providing a Sample Process from Activity Monitor as it's the only available information I can provide.

Can sharing a Spindump file from the Activity Monitor help in understanding the problem better?

Steps to reproduce:

Open the web browser.
Keep a few tabs open.
Continue normal browsing activities.

Expected behavior:

The web browser should operate smoothly without freezing or causing excessive CPU usage.
Tabs should remain accessible and not be lost due to the browser freezing.

Orion, OS version; hardware type:
Version 0.99.125-beta (WebKit 616.1.22); MacBook Air (macOS Ventura 13.6 build 22G120)

Leirk Can you please try OrionRC? (accessible if you join discord and ping me there, if you don't already have it) Also can you try with a clean new orion profile to rule out any extensions you may have installed fromc ausing this?

Steps to reproduce:

Open 30 tabs in Orion
Make the device fall asleep
Wake up the device and check CPU usage in the first 10-20 seconds
Orion uses a lot of resources which leads to lags during the first 10-20 seconds
*It doesn't happen all the time, not sure yet how to reproduce but maybe others saw it as well

Expected behavior:

Orion shouldn't require such CPU usage during waking up

rosenrot Can you show a video of that (activity monitor?) And compare it to Safari in same circumstances?

Is this with or without extensions?

Magebarf

rosenrot on your end, is the behavior noticeable even prior to logging in/unlocking?
On my end the password unlock screen is extremely sluggish when this happens, giving a hint about what's to come.

rosenrot

Vlad without extensions. I just posted it here because it came to my eye several times last week as I use Orion as my daily browser.

I need a little more time to reproduce and to compare to Safari. I thought it would make sense to post it here because maybe someone else experienced it already. This would help to narrow the potential issue.

Vlad

rosenrot I use Orion all the time as you can imagine across multiple laptops and do not have such issue. So we need to get to a reproducible state.

rosenrot

Vlad Of course I'm certain that you use it every day.

Actually, it doesn't happen when opening 30 tabs, putting the MacBook to sleep, and waking it up. It happens when I leave the laptop and it goes to sleep by itself. Meaning, when I return after an hour.

I have to investigate a bit what the difference is between putting it to sleep and falling asleep by itself.

Do you know if there are different treatments for apps regarding moving it to memory or something similar?

I will post steps to reproduce as fast as possible.

Magebarf

I'm also experiencing something very similar...

After M1 Mac Mini goes to sleep (I usually don't force it to sleep, as I don't have a laptop lid to close, so it gets to time out on its own) next time I log in a huge amount of kernel_task activities are going on, spiking the CPU at around 100%, the amount of time is variable, but as a general rule of thumb the longer the Mac Mini has been sleeping the longer and also to some degree the more severe the issue is.

Quitting Orion during this 100% CPU phase has so far always brought down the CPU usage of the kernel_task, so I'm not sure if it's swap or cache reloads or exactly what's going on behind the scenes.

Today the Mac Mini had been allowed to sleep all day yesterday, so it was quite a drastic effect.
A little slow to react I managed to take a screen shot of the Activity Monitor a little after I had quit Orion, which clearly shows the CPU graph taking a sharp dive:

The leftmost mountain is while Orion was stil awake, and the within a second of Orion quitting and the processes dissapearing from the activity monitor the CPU usage disappears.

rosenrot

Magebarf wonderful. I wasn’t able to reproduce this issue until now. What you say is what I experience as well.

I have the impressions the more tabs are open the worse it gets besides sleep time.

When my macbook wales up, the first seconds it is at 100% of cpu usage. Closing Orion vanishes the cpu usage for me as well.

I tried to use some tools to trace cpu usage, maybe this is the way to go to provide information about this issue.

Magebarf

Woke the Mac Mini up this morning, same thing with CPU pegged at 100%, and this time I managed to catch the behavior that lead me to suspect Orion as one of the reasons the kernel_task is spiking as well:

The items I'm thinking about is all the "Orion Web Content" with or without "(Prewarmed)" suffix. After wake up, the entire visible dialog is only this type of process listed below the kernel_task, and only once the CPU loosens up a bit (which is the case in my screenshot, as the Cmd+Shift+5 screenshot tool won't really show up until there are some spare cycles) does other processes start being listed in the top when sorted by CPU. Also as you can see, the slope going down shows we're in the tail end of that CPU "sausage" in the graph...

rosenrot

Magebarf Nice! I posted this issue here with the hope that other people would experience it as well and that with joined effort we can identify the issue. Seems we are making progress.

Magebarf

And a second follow up; Left the Mac Mini sleeping since morning, and actually had the Activity Monitor in the same place, meaning the Cmd+Shift+5 section was already pre-selected, and now I managed to catch the process list a little earlier, with more margin before the CPU pressure was lowered:

Now you can definitely see the reason why I'm assuming the Orion activity is what is hiding behind the kernel_task usage... 🙂

Vlad

Does Safari in same circumstances behave the same?

Magebarf

Vlad I will try to see what I can do to compare with Safari's behavior.
Haven't really been running Safari much since I've started using Orion, so my attempts will probably be "synthetic" at best.

(As a side note, more as a curiosity, I can add that I had similar wake-up behavior on my previous Mac Mini 2012, so x86_64, running Firefox, which had a long running bug spanning plenty of releases: https://bugzilla.mozilla.org/show_bug.cgi?id=1415923 )

rosenrot

Magebarf Exactly how you describe it. The login screen is already extremely laggy beforehand. This is how I identified the issue originally. I didn’t see this laggy behaviour on my brand new macbook before. It took me a while to identify Orion as its source.

In general the login takes not even a second but having Orion open makes it lasting 5-10 seconds on my end.
