 Posted: Fri Dec 29, 2023 11:15 am Post subject: Stuck in hibernate performance |
 |
|
I recently bought a new AMD Ryzen system and wondering why the performance of hibernating the system with kernel based swsusp is still poor.
The setup is classic with an 1:1-ratio of ram to swap, the latter is a dedicated device on an NVMe storage. As far as I know, hibernation works like that:
1. Make a kind of freeze and snapshot the memory
2. Compress the stuff from 1.
3. Write the stuff from 2. to disk
What I guess is that stage 2. is way behind its potential. Maybe the compression stage is done only with 1/8 of available cores or worse, with only 1/16 of available threads. Stage 3. is performing sufficiently and needs only a few seconds as indicated by the blinking storage led of the computer case.
Question: Is there anything I can do to debug my guess? I read the gentoo and arch linux docs very carefully plus https://www.kernel.org/doc/html/next/power/basic-pm-debugging.html , but I don't think the docs cover my issue. And is there anything I missed at kernel configuration all the year? The related setting are as follows:

I'm not sure it compresses. Still, freezing tasks, powering off devices and preparing the memory image takes some work.
You can try: | Code: | | # echo 0 > /sys/power/image_size |
to force a smaller image. Write/read time is not an issue for you, but maybe it also takes less time to prepare a smaller image ? I don't know.
It would be a tradeoff. Quoting from the bottom of Documentation/power/swsusp.rst: | Quote: | Q:
I upgraded the kernel from 2.6.15 to 2.6.16. Both kernels were
compiled with the similar configuration files. Anyway I found that
suspend to disk (and resume) is much slower on 2.6.16 compared to
2.6.15. Any idea for why that might happen or how can I speed it up?
A:
This is because the size of the suspend image is now greater than
for 2.6.15 (by saving more data we can get more responsive system
after resume).
There's the /sys/power/image_size knob that controls the size of the
image. If you set it to 0 (eg. by echo 0 > /sys/power/image_size as
root), the 2.6.15 behavior should be restored. If it is still too
slow, take a look at suspend.sf.net -- userland suspend is faster and
supports LZF compression to speed it up further. |

| In-kernel hibernation will compress unless instructed not to, via hibernate=nocompress on the kernel command line. |

Interesting hint! I switched off the compression, but the only noteable effect was the faster resume time.
So, what's happening before wirting the RAM content to disk? Maybe checksum'ing the stuff? And is it thread-safe? |

| I seem to recall that when last I looked, it was inherently thread-safe because it used only one thread. I have no answers to your other questions. |

As an aside, I'd consider increasing swap allocation to at least twice real memory size - unless you have constrained hardware, it's unlikely to be a significant loss of disk space. It needs space both for whatever the kernel has decided should be paged (and all sorts of things might kick that off, such as trying to compile qtwebengine and something else at the same time), and for the hibernate image. It's even possible that trying to fit the contents of ram into the available swap space is making it take longer than it might.

Thanks for the advice! I tried to understand the entire procedure bei reading https://www.kernel.org/doc/Documentation/power/interface.txt. My setup doesn't lack of both RAM and Swap space. When I buy a new system it should last at least a decade or more, so RAM is currently 64 GB what is the half of possible amount limited by motherboard.
Even if I double the image size limit to 4/5 of available RAM that should hopefully lower the "optimization" before things are written to disk, it still needs a too much time. |

Freezing processes. Does the system exhibit similr behavior on shutdown? Do you have some fancy services or optimizations made? Eye candy like plymouth et.c.?

No eye candies. Regular shutdown is fast.

Is it really freezing, that slows down things? |

Your output says freezing took just under 0.1 seconds, so no, I don't think freezing is a problem here.
What happens if you shutdown, then boot clean, start as little as possible (no browsers, preferably no GUI at all), log in as root on the console, and hibernate from there? Is that fast or slow? It should have very little memory to save, so I would expect that to be fast. |

Some "specs",
console login as root:
systemctl halt: < 7 sec
systemctl hibernate: ~ 18 sec, thereof IO activity ~ 7 sec (as indicated by board's LED)
Full plasma session with Firefox, Thunderbird, LibreOffice, Signal-Desktop:
systemctl halt: < 10 sec
systemctl hibernate: ~ 55 sec, thereof IO activity ~ 9 sec (as indicated by board's LED)

Took ~20 seconds to hibernate with firefox, 2 instances of IntelliJ and a few small apps like evince, gnome-terminal et.c. Ryzen 7 5800H with 32Gb RAM, 64Gb swap and NVME SSD here. What's your hardware? Ryzen is too broad as hardware description.
p.s. the swap space is twice the RAM as I initially intended to upgrade the RAM to 64G, but it turned out to be unnecessary.

Are you serious? Please share RAM size and storage type.
p.s. You seem to be caught up in your belief it's the CPU that's causing it. Drop that idea, the problem is not there.

As already mentioned, Swap is on NVME, recently extended to twice of available RAM size of 64 GB, following your suggestion. |

That wasn't a suggestion. That was stating just stating the facts about my measurement. Your responses are kind of implicit. I should imply what you mean. So your ram is 64GB, your swap is 128 GB?
Do you use any proprietary binary drivers like graphic or wifi/ethernet driver?
Is this a laptop or a desktop computer? If the latter, what is the motherboard?
Also it could be useful to share the output of free command prior to a hibernate.
BTW initially I intended to use hibernate but it turned out to be slower than shut down/start up and most of the time I'm suspending my laptop. For me hibernation was a thing back when I had a computer with 64 MB of RAM...
EDIT: with the above I'm suggesting that hibernate might not be good solution after all, you may as well reconsider the reasons you settled on it.
EDIT2: I don't see any significant difference of your kernel config in the shared area to mine. One puzzling thing is why mine, without debug enabled, print absolutely the same amount of information as yours. Are you sure you're running the kernel compiled with that particular configuration?

I don't see anything out of the ordinary. My mem usage was nearly 6Gb, yours is a bit over 8, I don't think this is a significant difference. One thing that puzzles me is your kernel with debug enabled does not give more information than mine.
Do you use something like disk or memory encryption? Although the increased IO in this case should not be the issue as you report the led indicates disk IO for only a few seconds.
I'm out of ideas. I hoped there would be a lead in the information I requested, but I don't see one. Maybe share your kernel config for someone more kernel savvy to check.
EDIT: actually the syslogs may contain more information like getting stuck on a service or something.
EDIT2: actually now that I measured it with a stopwatch, it's 35 seconds to hibernate and ~25 seconds to wake up. After all this might not be an issue at all.
| Code: | total used free shared buff/cache available
Mem: 27Gi 6.1Gi 17Gi 118Mi 3.5Gi 20Gi
Swap: 63Gi 1.4Gi 62Gi

I don't know why swap is used, maybe because of the hibernation.
Best Regards,
