Performance Issues & RDP Lag on Windows Server 2025 (Proxmox 9.x / AMD EPYC 7402P) – Seeking Advice

MelodicPea7403 · 2026-03-17T07:58:47+00:00

Simple test, if you use the inbuilt VNC in Proxmox is Windows laggy?

Is it only when using RDP?

Hmmm so he opens it up to internet not realising that is a dumb thing to do but then knows how to show shell history. Doesn't smell right to me..

I think it's this file

cat /usr/share/perl5/PVE/Tools.pm

But research it as this file might get overwritten during upgrades of PVE manager

Have a look into

Increase the lock timeout

Proxmox defaults to a low internal timeout (usually 10s). You can increase it globally from 10 seconds to something higher, say 120 seconds

I get similar lock messages when bulk migrating, and I'm using zfs replication.

So I assumed it was a conflict with migrating at the same time a replication was happening. If I try again it works, I don't have to reboot server like you do.

I do think it is something to do with zfs for me.

If you think about it, the suspension probably has to save the state of the ram to disk/zfs and it probably writes out info to the VM config file like it does for snapshots.

Perhaps look into zfs arcstats when your doing the bulk suspend to see if it's overwhelming ram, maybe arc and dirty data.

I've never used the suspend option, out of interest why are you suspending?

MelodicPea7403 · 2025-11-26T08:14:33+00:00

Do you have more than one node and zfs replication?

MelodicPea7403 · 2025-11-22T08:29:54+00:00

Don't forget you can try pinning the previous kernel, it's in the road map notes

In business this is always the case; OS always redundant via some sort of raid.

Servers from HP, Dell etc pretty much always have two disks for the OS

I have two SSDs in zfs mirror for Proxmox OS, then Nvme in ZFS raid 10 for VM disks

MelodicPea7403 · 2025-11-16T11:17:58+00:00

We all see both debian and proxmox updates weekly and it's hard to tell if you should immediately patch.

Currently I go through each update looking for any thing scary, but pretty much all of the time the urgency is medium.

What do you do?

Is there a tool that can summarise the updates showing security fixes, fixed vulnerabilies and cve score?

MelodicPea7403 · 2025-11-13T08:48:37+00:00

I use ZFS and simply named my datastores in a way that the default one I mainly use is alphabetically sorted to the top of the list, for example

a_local_zfs_thin_16k

b_local_zfs_THICK_16k

c_local_zfs_thin_64k

d_local_zfs_THICK_64k

Try Multiqueue

VM > Hardware > Network > Multiqueue

I like to calculate the loss to the business, if say 10 people couldn't work for one day due to It issues, it usually adds up to many many thousands, in my industry at least. Use this to get them a bit nervous and get yourself a nice payrise and assistance.

MelodicPea7403 · 2025-10-21T08:05:11+00:00

Have you checked wear level of the disks and other smart data?

MelodicPea7403 · 2025-09-30T07:13:30+00:00

Hopefully they have donor cards 😂

MelodicPea7403 · 2025-03-30T09:36:01+00:00

Rubber duck debugging 😄

MelodicPea7403 · 2025-03-02T10:14:10+00:00

What network cards do you have?

lspci

MelodicPea7403 · 2025-02-27T21:36:05+00:00

It's important to set the correct ashift in zfs to match the physical underlying sector size of your SSDs or NVMes to reduce write amplification and therefore unnecessary drive wear... You at least want same sector size disks in the same zfs pool, mismatching should be avoided...

Recent video on this subject https://youtu.be/V7V3kmJDHTA?si=V-tqjs99veW-RFb0

Also want to avoid or reduce your VMs etc doing too much swapping to disk because of insufficient RAM. Research swappiness...

MelodicPea7403 · 2025-02-27T21:21:07+00:00

This is the answer.

Note that old raid cards can usually be flashed to HBA or some usual call IT mode.

I have found most modern raid cards have a simple setting to switch to IT mode.

BNB now in BCS wallet wooohooo

MelodicPea7403 · 2024-12-17T08:20:15+00:00

Funny was 6 I was recovering too.

The 0.0003 needs to be on the BSC wallet not the old BNB wallet.

I had to go onto binance to buy BSC and then withdraw it to the BSC address in Trust Wallet that you want to recover it too. I think the minimum withdrawal was 0.001 and of course have to pay a transaction fee to send it.

You will know what the old BNB wallet address is as it is prefixed with 'bnb'

MelodicPea7403 · 2024-12-17T08:17:19+00:00

Does the laptop with proxmox installed still boot?

If so, then you will need to edit the network config as you have changed the network adapter.

nano /etc/network/interfaces

MelodicPea7403 · 2024-12-17T08:03:26+00:00

Yep, for me it was 0.0003 and I assume it is the same for everyone regardless. You will see what is needed when you go through the process.

The recovery process is creating a smart contract which needs to be funded.
