Hello. We are facing some problems with very poor CIFS performance.
Internet speed is 1Gbit/sec. We have cloud storage which is mounted to our pve cluster nodes.
Backup/Restore was very slow so we decided to do some tests

dd to cifs mounted storage shows around 6-8Mb/sec

Regular wget from pve nodes shows around 80-90Mb/sec
dd to lan NFS mounts - 120Mb/sec
disks are in raid 10
pveperf shows BUFFERED READS: 294.40 MB/sec

cifs mount options:
/storage/backup on /mnt/pve/backup type cifs (rw,relatime,vers=3.0,cache=strict,username=user,domain=,uid=0,noforceuid,gid=0,noforcegid,addr=x.x.x.x,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1)

For testing purposes we installed proxmox on cloud server and mounted the same storage via cifs.
Doing the same dd test and result was around 130Mb/sec.
Its a bit confusing, because mounting options, internet speed and other parameters is identical

Any help would be appreciated

Latency also plays a role in smb storage.
Is it possible to create a cifs share on your cloud proxmox server and mount it on your server?
It might just be slow on smb due to latency in your internet connection.

Thanx for reply. We also done this before. Speed was around 12-15Mb/sec.
So, its obviously a networking issue
