Proxmox VE 8.4 released!

[VictorSTS]

Since the upgrade, i have very slowly VMs (all) (windows & Linux) in all my server

Did you try to boot with the previous kernel?

Check the speed of the CPU with grep MHz /proc/cpuinfo if it is able to reach nominal/turbo speeds. I've had a few cases (unrelated to this update) where the CPU for some reason can't raise it's speed (faulty PSU, BIOS gone mad, faulty cooling). If it can't reach at least nominal speed, it will lack capacity, hence increasing the load and making everything slow.

(I still have a few LXCs to check - but haven't had the time as of yet).

I've now tried all my current LXCs & VMs, including some really exotic ones - and I'm happy to report smooth sailing!

In my testing - I am happy to report that I find the system as a whole - even snappier than before!

Hat off to a truly champion-team!

Awesome news. One feature I'd like to see is an easier way to share GPU (or partials) with LXC for things like LLMs so I don't have to dedicate a whole card to an LXC that may not be running all the time. Maybe this is already possible but it seems it's a cumbersome process with some mapping user/groups and all this rigamarole that I could never quite get working... If there's a more recent guide to set this up, please point me at it.

I worte a tutorial about it that yo can adapt for your needs. It goes through the basics of passing an AMD card to an LXC with Proxmox's new-ish feature implemented a few releases ago.

I have a stopping Proxmox installation here - sorry, I am new to this. How to downgrade to the prev. kernel. Can you help, please

I use NFS to mount a directory in my Debian VM and I tried the new virtiofs. It was around the same. Is that expected?

virtiofs
sudo sync; sudo dd if=/dev/zero of=/mnt/test/output conv=fdatasync bs=1G count=5
5+0 records in
5+0 records out
5368709120 bytes (5.4 GB, 5.0 GiB) copied, 6.29989 s, 852 MB/s

NFS
sudo sync; sudo dd if=/dev/zero of=/pve1storage/output2 conv=fdatasync bs=1G count=5
5+0 records in
5+0 records out
5368709120 bytes (5.4 GB, 5.0 GiB) copied, 6.1124 s, 878 MB/s

Not a scientific test by any means, but am I missing something or is NFS already getting the best out of my NAS? Appreciate your time replying to my question
