16. Branchcache – best practice & tweaks
Make sure the hash cache is big enough on the server
Content Size/2000 ish – also move off C drive
Always use ConfigMgr UI to enable BC
Set a big cache size in Windows 10 – it can shrink
Change the default port on clients – use the 2Pint TS
Lower the default content size on the server (64k by default)
If mixed Win7/10 scenario – consider BranchCache versions
Use the free 2Pint BranchCache for OSD Toolkit
Use correct BITS policy for optimum LAN tx speed

17. Branchcache – policy downloads in Configmgr
CB Can now P2P Policy – Hurrah!
BUT Policy is small and the BranchCache default is 64k
Change it to 4k via Registry on MP only
HKLM\SYSTEM\ControlSet001\Services\PeerDistKM\Parameters - MinContentLength

18. Peer cache – best practice & tweaks
Select Peer Cache sources (SuperPeers) carefully
Careful with the SCCM BITS policy – it can limit PC transfers between subnets
Same subnet = FG Prio, Intra subnet = High Prio (i.e policy will apply)
Use GPO instead
For testing – use 2Pint triggerhappy.exe to lower the reporting interval
See this blog for methods to select PC clients

19. DO Windows 10 only Fast becoming preferred downloader/P2P option
Uses Tracker service – must be able to get out to internet
Junkie downloader – will use lots of B/W
Many GPO’s to tweak
