performance

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...

On my proxmox machine I got two SSD drives natively connected to it. First disk is for proxmox OS, the other I want to use in VMs. Basically, I want to use half of this second SSD drive in one VM, and other half in another, preferably with auto-adjusting sizes (in case one VM needs more than a...

Ich betreibe 2 Cluster, 1X tolles neues wo alles erwartungsgemäss funktioniert, aber einmal ein günstigeres Setup was in der VM aber eine meiner Meinung nach viel zu schlechte Performance abliefert. Einmal die eingesetzte Hardware und Config: Wir hatten das Synology NAS in Verdacht zur...

Hi all, I'm currently running one PBS for my cluster, which stores data on an NFS share backed by an enterprise-grade QNAP storage. Everything went fine until about two weeks ago, when I noticed some scheduled backups were starting to file sometimes. Also, I see that when I browse VM backups...

Hallo zusammen! Setup: 9 Nodes, 53 LXC, Ceph-Verbund aus HDDs mit SSDs als Cache, einige Maschinen haben ein lokales ZFS (SSDs) als Cache. Prinzipiell ist die Performance gut und wir können uns nicht beschweren. Leider sind aber Folgebackups recht langsam. Beispiel: LXC foo: 100 GB/400 files...

Many discussions have compared Proxmox and VMware from a feature perspective, but almost none compare performance. We tested PVE 7.2 (kernel=5.15.53-1-pve) and VMware ESXi 7.0 (update 3c) with a 32 VM workload to see which performs better under load with storage-heavy applications. The results...

Hi Guys, is VirtIO Block (nicht VirtIO SCSI) still the best choice for performance? I'm talking about a 4 node cluster with around 200 guests on a ceph storage. Cheers,

I've got four HP DL360 G9 servers, which I intend to use in a hyper-converged cluster setup with CEPH. All of them are of the same hardware configuration: two sockets with Intel(R) Xeon(R) CPU E5-2699 v4 processors @ 2.20GHz (88 cores per server in total), 768GiB of registered DDR4 RAM...

I the continuous process of learning about running an pmx environment with ceph, I came across a note regarding ceph performance: "... if running in shared environments, fence off monitor processes." Can someone explain what is meant by this and how does one achieve this? thanks!

Saw a mini PC with a Ryzen 7 3700U. I know that this processor is outdated, may this device consider small power consumption but big processing power? My main purpose is to install OpenWRT on the Proxmox as a Internet router. May simply learn docker, container and linux, use the virtual machine...

Hello all, We have a following Proxmox setup: One storage server, HP DL380P G8, CPU Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz, 32GB RAM Storage Pool assembled on 8xSSD, Samsung SSD 870 QVO 1TB, which are put into the four mirrors with 2 drives each, and then mirrors are setup into the stripe...

Hello, I'm not sure if this is normal. PVE is reporting almost 50% RAM usage (out of 56 GiB) while all I have running are 2 lxc containers which combined have under 1 GB of RAM allocated. I do have a Windows 10 VM set up but it is stopped and its RAM is from 8 to 24 GB. When I use top to see...

Hello, I've found a few threads about similiar problem but none of them have a solution. We have a 3 node cluster with multipathed iSCSI storage using IBM Storwize SAN. In Proxmox 6.4 which we use, there is a shared LVM created which stores VMs on all nodes. We didn't notice any performance...

Hello all, We're looking for Best Practices regarding setting IOPS and Throughput limits on "Hard Disks" in proxmox. There's obviously limit and brust settings under Advanced on a given disk. Questions we have: Is there a way to see, from the Host level, the current IOPS/Throughput a...

Hello. I assembled mdadm raid0 from two Samsung 970 Evo plus NVMe SSDs, created an LVM VG on it and gave the thick LV as a virtual machine disk based on Centos8. On a hypervisor, this RAID delivers about 7GB/s read performance. When I test inside the guest OS with: fio --readonly --name=onessd...

Hi All, Hoping to gain a better understanding of why I'm seeing a difference in performance running the same fio command in different contexts. A little background, my pool originally consisted contained 4 vdevs, each with 2x 3TB. However due to a failing disk on mirror-3 and wanting to...

Hello everybody. What is the best processor configuration (VM performance) for these specifications? I'm using "host", I intend to create a replication with the same specifications in the future. Should I change the processor of each VM?

Hello there, I'm currently working with resolving some performance issues on a Proxmox installation. There is a ZFS array on the network which is hosting the VMs, and the behavior is strange. Currently, the server is hosting 3 Windows 10 VMs with the configuration shown in the attached image...

Hi All, I installed proxmox (using ext4 filesystem) on a 5212MB SATA SSD (used consumer-grade Sandisk SD8SB8U512G1001) to evaluate it. I run some benchmarks using fio, to get an idea of how fast it is. Before installing proxmox, I benchmarked the disk with PassMark's Performance Test on Win1o...
