slow

Hello everyone! I've recently started using Proxmox on a machine with the following specifications: Processor: Intel® Xeon® Processor E3-1220 v2 RAM: 8GB Storage: 1TB SATA HDD I'm only running one virtual machine at a time due to the hardware limitations. However, I'm experiencing some...

Hello ! I've been struggeling with one of my servers for several months now. There seems to be a hardware conflict related to SATA. My ZFS RAIDZ (4x 10TB HDD in 2 mirrors) claimed that there was 1 disk failure. I replaced the disk and shortly after, 2 more disks seem to fail (one in each of the...

Hello, I am experiencing a very slow Windows 10 VM on Proxmox 8.1. Proxmox 8.2 would NOT install on my Dell R610 dues to some undocumented bug. Dell R610, 24 cores, 96 GB RAM Proxmox 8.1 Click on task manger or file Windows Explorer, it pops up 10 seconds later, very unresponsive, but not...

I have a Ubuntu 24.04 VM setup in Proxmox VE 8.2.4 on its own SSD and for some reason, file transfers to my local Truenas Scale SMB share are stuck at 55-60MB/s. I ran a Iperf3 test to the NAS and it caps out at 110MB/s so it's not a limitation of the network. This VM has 6 Ryzen 4600g cores...

I'm having some trouble with backups on my Proxmox cluster and I'm hoping someone can help me troubleshoot. I've been searching for solutions online for a while now, but I haven't been able to find anything that helps. Here's my setup: 3-node Proxmox cluster Backups to both a NAS and a PBS...

Alright context. I have 2 nodes in a cluster. Dell R620 Dell R720 Going to talk about 3 devices total. All have 10Gb networking to each other through a switch Both machines are running the same pve version (8.1.10) and kernel versions, both are fully up to date Both machines have the same...

Good afternoon dear, I have a problem with about 3 nodes of which all share a 10g fiber link for migration and vms backups. but even if the vms migration and restoration are slow some reason why so little speed 3 nodes config network nodes cluster config slow restoraution vm...

Hello, I just migrated pve7 to 8. Every VMs work well except two Remote Desktop Services VMs which are slow, especialy in Excel. I'd like to know if anybody had the same problem and if someone has some ideas on how to solve the problem. regards

Hello everyone! I'm no storage expert but I do observe some subpar disk performance on Windows (I have some linux I can test as well but I didn't notice anything while using them). We use ZFS and we disabled balloon and tablet following https://pve.proxmox.com/wiki/Performance_Tweaks Here is...

Hello there everybody, i am running an Windows 11 VM on my proxmox server (newest BIOS and all settings double checked on the BIOS side). I use a i9 13900k and 64 GB 3200 mhz DDR4 RAM. Somehow no matter what i am doing i get disappoting multicore benchmark results in the Windows 11 VM. I tried...

This problem has been rumbling on a while, lots of trace messages about delays, ceph being "flakey", very slow VMs, kubernetes clusters taking 30 min to come up etc. We migrated one VM with Kubernetes onto a little bit of NVME local-storage and at the moment, the view its that is has come...

I am wondering if anyone can help me debug, I have both UNRAID and prox running. Server has 2x e5-2699v4; 768gb ram. (HP dl380 Gen9) Unraid has ryzen 5 3600, 64gb ram I replicated the same setup I had on unraid as close as I could, but even after a lot of changes and iterations with my prox...

There is an ongoing discussion about slow encrypted ZFS performance, e.g. here: https://github.com/openzfs/zfs/issues/15245 and here: https://github.com/openzfs/zfs/issues/15276 Obviously this is due to a regression introduced in kernel 5.15.0-82 and discussed here...

Hello, there is a problem with LXC containers on my setup. When trying to use docker or use systemctl, the executables are just freezing for a couple minutes without cmd output. lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Address sizes: 48 bits...

I created a VPN service using OpenVPN and I was trying to figure out where the bottleneck is because it's very slow compare to the internet speed I have on the server. But during the process I found things very confusing (the sevice is in LXC): 1. speedtest in the PVE host and LXCs have much...

Good morning all. I just rebuilt my Proxmox server after a hardware failure (bad SSD). I'm up and running again witn Proxmox 7.3-1. I'm running into an issue with the backup function. I started a backup of 5 VMs last night. As of now, 12 hours later, it has still not finished! No errors...

This issue has been solved. This thread is for anybody having slow I/O performance and searching for keywords. The cause might be ZFS trimming the rpool. I’m running proxmox version 7.3-1 on a Supermicro A2SDi-8C+-HLN4F with HP SSD EX920 1TB for the rpool. My proxmox node was unresponsive. VMs...

I have read all the forum posts related to slow GC. I have to bring this topic up again and ask for help. I use PBS 2.3-2. The work of the disk subsystem does not cause any complaints. Carried out the tests: 1) with copying a single huge file. 2) unpacking their documents from the archive to...

hi everyone, I'm trying to install a lancache server on a "brand new" proxmox server with a 10gbit network connected to a 10 gbit server. I tried to configure a zfs with two raid1 ssd, single ssd, single hd when I try to sftp a file to the proxmox server (add iso and so on) I receive 100MByte /s...
