I just updated to 25.04.2. I am experiencing a problem that I already had when I tried 25.04.0 (after which I moved back to 24.10 because of virtualization issues). My whole NAS performance is extremely poor under 25.04.2. The UI feels less snappy, stuff on CLI takes a long time (just launching h…

That is an entirely different issue then. And its always been this way on any 25.04 version? Could be with the newer LTS kernel we shipped then still. Are you willing to smell-test a nightly of 25.10 to see if the updated kernel there helps any?

[image] Captain_Morgan: Can you collect the metrics like boot time … post them here. I calculated boot times from syslog (from the first “Linux version 6.x…” to “Reached target truenas.target”). 24.10.2.3 (with my init tasks that might slow things down a bit): 1min23s 24.05.2 (without any c…

I am, if I can just boot back to 24.10 without anything broken/migrated by the nightly :sweat_smile: If i have to reinstall and restore a config from before the update that’s fine too. The only thing that would be a no-go would be something that changes my application data or VM zvol or something …

Yes, you can update and then roll back. Just need the datapoint to confirm if the kernel is the thing in play here, or if something else is going on…

Okay, can I just use any current 25.10 nightly?

Go ahead and grab the latest: https://update.sys.truenas.net/scale/TrueNAS-SCALE-Goldeye-Nightlies/TrueNAS-SCALE-25.10.0-MASTER-20250801-015503.update

I have, will try this weekend, probably tomorrow.

I have now tested the 25.10 nightly. It booted up much faster again - 1m49s @Captain_Morgan . Not quite as fast as 24.10 but it was also the first boot on this version so… all absolutely fine. Also ix-vendor.service started fine on this version. Just to be sure I also generated another debug fil…

Excellent! Thanks for confirming. So likely it’s a transient kernel bug in the version we’re using on 25.04, probably specific to your hardware. The BETA for 25.10 will be dropping later this month, I’d suggest rolling back for the moment, but plan on updating to that when it lands and you should be…

Do you mean the BETA for 25.10? I’d really like to stay on stable though :sweat_smile:
