I've created another topic about 8 months ago and didn't get help, too : https://forum.proxmox.com/threads/backup-restore-low-speed-what-is-wrong.124426/

I didn't find solution, I'm still working on it. With iperf, I get about 8Gbit, but when I try to copy file between nodes, I get about 120-160MB/s , This is very much under storage performance.

I've got a question - I'm creating 4 nodes cluster, storage will be directory on every node, can I use the same name of storage on every node? Will it work? How to do it properly to migrate vms with local storage disks?

Thanks, I've found another solution - default action for files in FF is saving unfortunately and can't set it in extensions for vv.

Can anybody help with such case? I'm using Firefox, when I click console button, ff downloads vv file and then I can click it to open spice client. How to set browser to open it directly with one click? Maybe somebody knows?

What do you mean "with repo from pve1/sdb"? DL380 g8 has Smart Array P420 Raid controller and g9 has Smart HBA H240ar.

OK, I'm starting: Source machine (pve1): DL380G8 2xCPU 8core, 384GB RAM, RAID60 on SAS HDD, storage in directory. fio tests for rw fio --name=WriteAndRead --size=1g --bs={4K,64K,1MB} --rw=rw --ioengine=libaio --sync=0 --iodepth=32 --numjobs=1 --direct=1 --end_fsync=1 --gtod_reduce=1 --time_based...

Ok, I'll clear it, it's not config from first post. Machine I'm trying to backup is on my 1st pve - physical machine is hp dl380 g8, 384gb ram, 2x 8 core cpu, Sas disks on raid60 - storage for vm drives is the directory (so file based). Pbs is on 2nd pve: dl380 g9, 256gb ram, 2x 6core cpu, ssd...

OK, I'll do it tomorrow. I'll write everything about source and destination with fio tests (I've checked iperf, it was about 6-7Gbit between 2 machines).

I'm totally helpless - I'm trying to backup 650GB vm. Source is file based storage on raid 60 (hdds) + 10Gbit network interface. Destination is PBS on ssd raid 10 (Ultrastar SS300) + 10GBit network interface. Help me, please, how to diagnose that, I don't even have any idea what should I...

If I understood it clearly, on file based storage I should use block size of filesystem? Right? Or I can use any block size to emulate e.g. video streaming?

PBS is vm on Proxmox, storage is NFS from another vm (TrueNAS) on the same pve, I was trying to move disk to local pve storage but it will take few days, transfer is about 60MB/s.

I've used fio --size=8g --rw=randread --bs=1M --ioengine=libaio --iodepth=32 --runtime=60 --numjobs=1 --direct=1 --time_based --name=WriteAndRead --end_fsync=1 --gtod_reduce=1 on my pbs but it's showing transfers about 10GB/s. Why?

So I'll test all of my nodes and pbs servers (if I'll find what parameters should I use for these tests).

Do you mean fio? Or something else?
