speed

Hi there, Consider a 3 node setup with each node having 2x 10GB & 6x 1GB Nic. Is it more interesting to speedup replication between the nodes using 10GB interconnects and have the VM's communicate on 1GB (scenario 1) or is it more interesting to speed up VM <—> desktop access (scenario 2) My...

Hi all, I'm facing a strange problem. I'm using latest Proxmox with Ceph storage backend (SSD only), 10Gbit network, KVM virtualization, CentOS in guest. When I create a fresh VM with 10 GB attached Ceph storage (cache disabled, virtio drivers), I'm getting roughly these speeds in fio...

Hi, I installed a fresh Proxmox VE and tested the speed of the disk: root@pve:~# dd if=/dev/zero of=./test bs=1G count=1 1+0 records in 1+0 records out...

EDIT: As I find out that high IO will only result in freezing while performed on host, not guests please skip to post #19 as there are new findings. I'm basically reposting issue that I have with backups to FreeNAS from this post...

Guten Abend, ich sitze gerade vor "meinem" ersten Proxmox-Produktivserver und bin der Meinung, dass ZFS nicht in die Pötte kommt. Gerade getestet mit CrystalDiskmark sind es etwa 30 MB/s 4K QD32 Read. Ein paar Eckdaten zum Server und der Installation: CPU: Xeon E5-1620 RAM: 64GB, ZFS Max...

Hi, I don't know why but CPU speed seems to be very low. On a fresh install of pve5 with 2 x Intel(R) Xeon(R) CPU E5-2640 v3 @ 2.60GHz I have : root@dc-prox-06:~# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s)...

Hello. I have a Proxmox host and storage. Proxmox host Storage host Virtual machine Export NFS options I connected storage on PVE with NSF (1 Gigabit) and can not get a record speed of more than 40 MB/s within the virtual machine. But getting a full opportunity to record the speed of...

Hey, My servers have an internal rack speed of 1Gbps but an external speed of 250Mbps. Each time the backups start, it =saturates the network card and most incoming connections to the server drop (websites unavailable, etc). Is there a possibility, other then setting up a separate backup...
