latency

Hello Community. Does anyone have KINGSTON SFYRD 4000G drives in ceph cluster? We have built a cluster on them and are seeing very high latency at low load. There are no network or CPU issues. Ceph version is 17.2.7, cluster is built on LACP inter 25G network cards, Dell R450 servers, 256Gb ram...

I love Proxmox's ability to make it super easy to set up a three-node HA cluster with Ceph. I like to use it for my VMs and SQL databases that require a lot of IOPS. This way, if one of the nodes goes down, my SQL DB VM can be quickly redeployed to another node. That way, if one of the nodes...

Memory: balloon=0 Processor: Numa=1 SCSI Controller: Virto SCSI Machine: Default(1440fx) Network: VirtIO What else can I do to increase my VM latency?

Hey guys, in the latest Ceph blog a post was published on 13.02 regarding a CMAKE_BUILD_TYPE bug, which apparently affects Ceph Ubuntu packages. I know that we use Debian, but in a github pull request Proxmox is mentioned with a significant improvement in latency. Can we assume that we are...

Hi, We are using a three-node hyperconverged cluster. We are experiencing latency on only one of our nodes. On two nodes, latency varies between 1 and 5. On the last node it can be up to 300. PG autoscale is On and the Crush Rule : replicated_rule. The nodes are strictly identical: Dell...

We have a 5 nodes cluster and with atleast 4 disk in each node, may i know what’s the latency requirement between these nodes?

Hello Everyone. We received excellent feedback from the previous storage performance investigations, particularly the technotes on optimal disk configuration settings (i.e., aio native, io_uring, and iothreads) and the deep dive into optimizing guest storage latency. Several community members...

Hey everyone! Is there a way to display the latency among nodes, meaning from the node you currently are in (either console or WebGUI) to the rest of the nodes of the cluster? Like running the ping command to each node and displaying the end result together in a quick, useful and fashionably...

Several customers have asked us how to get the best possible storage latency out of Proxmox and QEMU (without sacrificing consistency or durability). Typically, the goal is to maximize database performance and improve benchmark results when moving from VMware to Proxmox. In these cases...

Hello. Are there any recommendations to help improve network latency? I'm using the latest version of PVE to test out OpenWRT in LXC to replace an aging router. Using Smokeping, I see my current router is around 200 microseconds and all network interfaces of my proxmox server is around 575...

Hi Everybody We have a 5 node proxmoxcluster with 800+ containers. We finally were able to upgrade from proxmox6 to proxmox7.2 this week After the upgrade all 40 Ceph OSDs went from 1-2 ms latency to 30 ms and up The latency went up when we bootet the servers into proxmox7.2 and ceph15...

Hi all, I'm having what seems to be a network nottleneck. Context is: one of my clients wants to revamp it's infrastructure and was happy already with PVE servers despite having only local zfs backed images, missing out on the broad possibilities offered by Ceph... I wanted to push him to go...

Hi, after migration of a Checkpoint VSX to VSEC Appliance on Proxmox infrastructure, seems that traffic passing through this firewall present an high latency and packet loss. Here an example: 2021-09-20 08:58:34 --- 100 packets transmitted, 98 received, 2% packet loss, time 99027ms --- rtt...

Hi. I have created a windows 2019 cloud init image, following this tutorial, and using that image, I've created a VM using cloud init parameters for network and setting password. The VM works, but there is a big problem. It takes around 10 minutes for cloud parameters to apply. That is how log I...

Hi Guys, so we have started using Proxmox, migrating from VMware, I currently have 4 Proxmox nodes in Cluster and already migrated almost 40 VM's. everything is working as expected, migration doesn't take that much. we are using a Compellent SC5020 as a shared Storage, VMware also uses the...

Hi all, We are having some strange issues with IGMP. We have a three cluster node running v.4.4 (latest stable) The Cluster is working and we have managed to have everything running. Server indicates that : Cluster: pmox-osnet, Quorate: Yes. Problem is that we have experienced a very...
