      @olivierlambert ok here's a bit from the log.. Start: 2025-09-03 12:00
      End: 2025-09-03 12:00
      Duration: a few seconds
      Size: 624 MiB
      Speed: 61.63 MiB/s

      Start: 2025-09-03 12:00
      End: 2025-09-03 12:00

      so other jobs are sowing anywhere betwwen 25 to about 80. MiB/s

      What CPU are you using? We saw about the same speeds on our older Intel Xeon's with 2.4ghz and when we switched to newer Intel Xeon Gold with 3Ghz the speeds increased quite a bit, we're now seeing around 110-160 MiB/s after migrating the XO VM.

          My hosts are Hp Elitedesk G5 SFF.. 64gb Mem Processor type is Intel Core i5 3.0Ghz i believe.. nics are showing connected @ 10GB

            IDK if the BIOS provides many power options, but you could make sure you are turbo boosting when needed. Because it's likely your CPU is both old but also not getting at 3Ghz at all.

              Great minds and all that, you know πŸ˜‰

              @utopianfish check if you have any kind of power options regarding "power saving" or "performance" modes you can change in the BIOS. That could make a big difference as well.

                @nikade i think the problem is its using the mgmt interface to do the backup..its not touching the 10GB nics.. when i set it under Pools/Adanced/Backup to use the 10gb nic as default the job fails... setting it back to none the job is successful with a speed of 80 MiB/s.. so using the 1GB mgmt nic... how do i get the backups to use the dedicated 10gb link then. ?

                  Use XO to connect on the host with the 10G network IPs addresses.

                    May I ask why your management interface is not on the 10G nic? There is absolutely no downside to having that kind of setup.

                    We used this setup for 7 years on our Dell R630's without any issues at all. We had 2x10G NIC in our hosts and then put the management interface on top of the bond0 as a native vlan.
                    Then we just added our VLAN's on top on the bond0 and voila, all your interfaces benefits from the 10G nic's.

                      That's also what we do in our prod.

                        I could be wrong but from VMware world the management interface didnt transfer much data if at all. It was only used to communicate to vsphere and/or to the to the host. So no need to waste a 10gb port on something only only see kb worth of data.

                        Our previous server had 2x 1gb nics for management 1x 10gb nic for network 2x 10tgb nic for storage 1x 10gb nic for vmotion.

                          Tbh I do the same on our vmware hosts, 2x10G or 2x25G and then the management as a vlan interface on that vSwitch, aswell as the VLAN's used for storage, VM traffic and so on.

                          I find it much easier to keep the racks clean if we only have 2 connections from each hosts, rather than 4, since it kind of adds up really fast and makes the rack impossible to keep nice and clean when you have 15-20 machines in it + storage + switches + firewalls and all the inter-connections with other racks, ip-transit and so on.

                          Edit:
                          Except for vSAN hosts where the vSAN traffic needs atleast 1 dedicated interface, but those are the only exception.

                            @nikade My 10gb nic are directly connected to my hosts.. i dont have a 10gb switch.. the mgmt is connected via switch ports...

                              @utopianfish I see, that explains a lot.

                                @nikade Yeah, that is a far from optimal setup. It will force the data to flow through the management interface before being routed to the storage NICs.
                                Running iostat and xtop should show the load. A better configuration IMO would be putting the storage NICs on the switch and using a separate network or VLAN for the storage I/O traffic.
                                Storage I/O optimization takes some time and effort. The type, number, and RAID configuration of your storage device as well as speed of your host CPUs, eize and type of memory, and configuration of your VMs (if NUMA aware, for example) all will play a role.

                                  @tjkreidl I think the issue is that he's got no 10G switch, hence the direct connection πŸ™‚
                                  But you live and you learn, best would be to pick up a cheap 10G switch and make it right!

                                    @nikade ok thanks.. that’s begs the question.. where can I get a cheap 10gb switch.. not sfp. Would need to be rj45 connections

                                        @utopianfish Or look for deals in places like amazon.com or bestbuy.com or even Ebay.com.

                                          @nikade Did the same. VLANs are great! We did use separate NICs for iSCSI storage. But the PMI and VMs, traffic was handled easily by the dual 10 GiB NICs, even with several hundred XenDesktop VMs hosted among three servers (typically around 8- VMs per server).

                                            @tjkreidl I have same results as you : ~80MB/s for backups over a 2x10Gb network bond.

                                            Only way i managed to get overt his 'limit' is by using XOproxies, on another VLAN on this SAME bond
                                            Don't ask me why, but bandwith tests (when you click TEST on a remote) tripled comparing to the remote on same VLAN as the XOA.

                                            Isolating is a better best practive for backup networks, but also has the benefit of getting more bandwith ? strange.

                                            My backups can now reach 100/110 MB/s (yeah tripled only in the test...)
