I haven't had time to throw more disks in but 1tb sata ssd for proxmox install + the standard "local" dir and "local-lvm" (thin) 1tb sata ssd for nothing but backups 1tb nvme sdd set up as a single lvm-thin for all guest vm root drives 2x Part 4 in a series of technical articles devoted to optimizing Windows on Proxmox. In short: benchmarking is a good tool for determining the speed of a storage system and compare it to other systems, hardware, setups and configuration settings. Hi, I have 2 proxmox clusters connected to a Unity SAN via 10Gbps Fibre networking, using NFS Shares on the SAN After weeks of troubleshooting random latency As I am just reading here and not using proxmox yet, these are from stock Debian 12, host and guest, reaching 75% of the native IOPS. 2 of the disk slots use RAID1 for installing the system, and the other 6 disk slots use Samsung . My proxmox host has 2 SSD's. Peak gains in individual test cases Hello I would like to know what measure proxmox use for virtual machine iops. Yes virtualization adds overhead, and I know that. But running the same test under VM drops performance by additional factor of ~3! Going from 84k IOPS under LVM on the host to below 7k IOPS zvol in VM is a slowdown by a FINDINGS Proxmox Offers Higher IOPS Proxmox VE beat VMware ESXi in 56 of 57 tests, delivering IOPS performance gains of nearly 50%. It is designed specifically for assessing I've setup a cluster and I would like to benchmark networking, corosync, ceph, disk and any other tools you think I should use to benchmark the cluster prior to moving VMs into Tried Proxmox with both the stock 5. 6 with minimal variations. Each data point collected Proxmox VE 9 is a powerful open-source virtualization platform combining KVM virtualization, LXC containers, and software The storage in our Proxmox Cluster was slowing down / IOPS were maxed out and Proxmox does not allow to see IOPS per VM. 2K SAS HDD in ZFS RAID 10, the other with 4 x 4TB SATA SSD in Z1 and they're coming out with near identical IO I use 4 Dell R740 8 SSD disk slot servers to deploy Proxmox in the lab. With this program Pveperf is a command line tool used in Proxmox Virtual Environment (PVE) to measure storage and network performance of virtual machines (VMs).

There's obviously limit and brust settings under Advanced on a given Hello, We recently got a NetApp AFF-A250 and we want to test NVMe over TCP with proxmox. Guest has only 1/2 GB, Host 32 GB We're looking for Best Practices regarding setting IOPS and Throughput limits on "Hard Disks" in proxmox. Tries to gather some CPU/hard disk performance data on the hard disk mounted at PATH (/ is used as default): simple HD read test. The end goal is to get a reasonable amount of write IOPS from the ceph pool built out of the 12 NVMe enterprise disks. g. There are 2 Ceph Pools configured on them and separated into a NVMe- and a SSD trueHello, i want to monitor the IO stats (% busy, r/W, etc) for each physical disk that's on the host, as i want to check if one of the SSDs is being slower or having a bottleneck as i'm having Hi there! I have two PVE 7. Using This is my issue. Both are bad if you want high IOPS because you only get IOPS that are below 1x the performance of a single SSD . 1. I'm having some trouble identifying where the performance issues are. GitHub Gist: instantly share code, notes, and snippets. For example when Samsung disk PM1643 says Random Read is 440k OPS, I can I setup a Proxmox cluster with 3 servers (Intel Xeon E5-2673 and 192 GB RAM each). This seems like a big reduction in IO Performance testing Proxmox Storage with fio. 3: iperf test between 2 proxmox nodes: 5Gbps (it's OK) IO benchmark from proxmox server to NFS: 22K IOPS (OK) So I did another test using a consumer ssd as a db/wal drive and performance across the ceph HDD pool shot up to 130iops. 2. I have a six-OSD flash-only pool with two devices — a 1TB NVMe drive and a 256GB SATA SSD — Hello, I have a problem with NFS performance from VE 4. Modern HDs should reach at least 40 I just used iperf3 to test network links, and fio to test storage IOPS to get an idea how performant the hosts, vms, iscsi targets and containers are, especially for big databases. Monitor IO of Proxmox Virtual Machines. I noticed that there is a hard limit within the VM, e. 2, Fri Dec 12 13:18:26 UTC 2025 Hello, I'm trying to evaluate the performance differences on storage between ESXi and Proxmox. One is for the host itself, and the other is for the virtual Disks for the VMs and containers. Without comparison, the benchmark is totally useless, therefore you need to have the same test environments and this page exists to lay This command runs a write test with a block size of 4K on For each set of Proxmox configuration options considered, we execute a battery of concurrent I/O tests with varying queue depths and block sizes. 0 on ZFS, one with 12 x 4TB 7. Best Use: Mixed-Use 4KB Random Read: 130000 IOPS 4KB Random Write: 39500 IOPS Server used for Proxmox: HPE ProLiant DL380 Gen10 - All the NVMe drives are Hello all, Can anybody help me understand the weird performance running on proxmox ceph cluster ? I'm having jmeter iops/sec performance test with my proxmox ceph Hi folks, I have a three-node cluster on a 10G network with very little traffic. We do have NVMe/TCP working on VMware and in a windows environment it Hello everyone! I am currently testing how we can get the best disk performance (IOPS) within a VM. In Part 4, we quantify and compare IOPS, bandwidth, and latency across a Raidz is like raid5 and raidz2 like raid6. x Kernel and also the upgraded 6. Best IOPS By which we can provide 8 of such servers at ease.
