WSUS Download Speed to slow since 2012 R2 up to 10 times faster
During my POC I need to bring a up to date WSUS to my customer dedicated environments with no WAN connectivity.
Every time I set up a fresh WSUS I had to wait 3 days after 20 GByte were downloaded with 2 MBit/s with a 100Mbit/s internet connection . That was and is to slow.
The reason is that the BITS configuration was changed from Microsoft. To speed up your WSUS Server you have to:
Install on your WSUS Server:
Microsoft SQL Server 2012 Native Client
Microsoft SQL Server 2012 Command Line Utilities
You can download them from here:
link
Then navigate to the new folder:
C:\Program Files\Microsoft SQL Server\110\Tools\Binn
Run administrative CMD:
SQLCMD.exe -S \\.\pipe\Microsoft##WID\tsql\query -d "SUSDB" -Q "update tbConfigurationC set BitsDownloadPriorityForeground=1"
or
.\SQLCMD.exe -S \\.\pipe\Microsoft##WID\tsql\query -d "SUSDB" -Q "update tbConfigurationC set BitsDownloadPriorityForeground=1"
Revert:
SQLCMD.exe -S \\.\pipe\Microsoft##WID\tsql\query -d "SUSDB" -Q "update tbConfigurationC set BitsDownloadPriorityForeground=0"

Storage Spaces Direct - Processor Compatibility settings
Found this comment in a MS BLOG for Storage Spaces Direct SSDi in Windows Server 2016 as VM
"Note: Do not enable the virtual machine’s Processor Compatibility setting. This setting disables certain processor capabilities that S2D requires inside the VM. This option is unchecked by default, and needs to stay that way. You can see this setting here:"
Take this tutorial for further information: link

Hyper-V Windows Server 2016 technical preview 2 from IGNITE 2015
New features in Hyper-V Windows Server 2016, not all Features are communicated until final release.
-
- Hyper-V is available on Nano Server
- virtual TPM Security
- Secure Boot for Linux (Ubuntu 14.04 / SUSE LES 12)
- Shielded VMs (encrypted by Bitlocker,etc)
- SoFS can now QoS IO by owner of the VMs - Important for Tenants
- Storage Resiliency with Resilience File Handle from SoFS. After 60 sec the VM is paused not crashed. After the network connectivity is restored the VM will restart running.
- Cluster Resiliency Feature: After a clusternode was removed from the cluster majority all VMs were turned off on this node. This was fixed by Isolation Mode for the VMs and clusternode, after the network came back the isolation mode exits and all VMs stay online.
- hotadd/ remove Memory static or dynamic configuration
- hotadd/ remove network adapter
- Upgrade from Windows Server 2012 R2 Cluster to Windows Server 2016 without downtime, with rollback function
- support for production checkpoints, VSS Snapshot for SQL,Exchange during taking checkpoint. After restore of checkpoint the VM , the VM starts with a clean boot. The application and OS interpret this as a normal restore.
- PowerShell from host OS to guest OS
- ReFS for VHDX Operations
- ReFS instance disk merge for checkpoints with zero data copy- this is really great
- ReFS instance fix disk creation
