I've used the Windows Performance Analyzer to record the behaviour and there was no special process, but System itself which was stopping to write anything to the disk: while the network speed was between 100 and 110 mb/s. Looking to the normal resource monitor I've seen that the disk write speed Oh nice - you were absolutely right! I never thought that this could be even the issue as there are 8 SSD disks, which provide the underlying disk system in a RAID 5 - but yeah. The hardware: HP Gen8 Microserver (Server A), HP Gen8 D元60p (Server B), Ubiquiti Unifi Switch 24 Portĭid anyone have had a similar issue in the past? And how did you solve it?

Disabled IPv6 on sender (I am using it actively in this network) Disabled Send Large Offloading IPv6 on sender (and later on receiver)

Disabled Send Large Offloading IPv4 on sender (and later on receiver) Latest Windows Updates installed (up to February 2020) Everything works as expectedĪ ping from one side to the other works perfectly. The error occurs mostly between 3 seconds after start - but sometimes there happens exactly nothing. The number of link down events does not change on the switch. Interval Transfer Bandwidth Retries CWND IPerf under linux (in a VM) shows some minor losses, but Server B is under active usage (1-10 MBit/s), so Congestion might occur. IPerf under Windows show nothing special. I've realized the issues as I was trying to copy a 200gb disk-file from one host to another - what resulted in a drop to 0 MBits/sec copy speed, which sometimes recovers, sometimes the operation is being interrupted. To undo this change, repeat the steps above, but type: netsh interface tcp set global autotuninglevel=normal instead.I have a very strange Network behaviour with my two Windows Server 2016 Hyper-V Hosts (Server A and B).

If file transfer is slow over a network and you have troubleshot everything else, such as updating the NIC driver, remapping drives, software impedance, and the router and flashing the BIOS, you might try the steps below. In Windows, this can be slowed down by "network auto-tuning". Many of our clients send large files over the network as a part of their day-to-day business. This problem is isolated to the internal network and external internet connection speeds were unaffected. How can I speed up file transfers in Microsoft Windows? Large file transfers are slow over internal gigabit networks. Slow transfers of large files in Windows.
