We used robocopy to transfer 2TB of files from a 2008 R2 physical server to a 2012 R2 virtual server. Testing the same file transfer outside a XenApp or XenDesktop session does not show any slowness. SMB's "transaction" mechanism is used to implement requests and responses that could transfer more data than the limited amounts some mechanisms over which SMB is sent allow in a single packet. Under heavy traffic load, with latency monitoring being enabled on the Sensor, some packets are corrupted causing retries and slow traffic. But, it's really really slow. Hyper-V virtual machines (VMs) hosted on a Windows Server 2008 R2 or Windows Server 2012 (R2) server may exhibit slow network performance if Broadcom network adapters are installed in the host. I'm trying to transfer large files from a Windows 7 machine to a Windows Server 2012 R2 box and I'm only getting around 45 MB/s. We remain in “Congestion Avoidance” mode for the rest of the file transfer, never seeing “Slow Start” again. All other network access (speed test/http/FTP/etc) are all normal speed, only SMB/CIFS access. There have been reports that setting socket options = SO_RCVBUF=8192 in smb. Copy to the NetApp NAS share 4-5 times slower than copy/paste to another server. Perhaps the uplinks are transposed to how you think they are. I am going to try and attach some Wireshark captures demonstrating a "fast" and then a "slow" transfer. If you have a KM-3050, KM-4050, or KM-5050 go to Scan to Email, Scan to FTP, Scan to SMB. Similar to AFP, SMB / CIFS were developed as native protocols for the parent operating system Microsoft Windows. Virtual Environment 5. The best explanation I have seen for this is that the Microsoft TCP/IP stack is slow in sending TCP ACKs. Output of 'top' command shows 100% SoftIRQ during the file transfer. SMB being about half as slow as regular SFTP. Unfortunately, the file transfer speeds are so bad you’re considering buying a turtle and glueing a USB drive to its back to speed up file copying.
