Recently been tasked with migrating a fair ton of apps from Win7->10. One of the challenges in this space is testing. Previously with Windows 7 the guys worked on static persistent VM’s rolled out to testers to run their updated app through it’s paces. Few obvious problems with this approach
I) Quite a bit of VM admin to do – clean up post test of apps
2) Quite a bit of email admin to do – separate mails tailored for specific app owners detailing their specific machine to test etc
Luckily things have moved on a bit most importantly regards “delivery” of the apps. By that I mean previously was hamstrung with only allowing a VDI-type scenario being of use to cover app-v sequenced apps as they where using the “follow-the-user” model (user added to SCCM user collection and deployment type set to include VDI. As such at the time experience was limited with app-v which meant a VDI solution wasn’t practical for testing as vast majority of apps where MSI’s.
To that end we have been able to get over that hurdle by publishing the MSI’s as applications in SCCM rather than packages this gives us the flexibility to use the same follow-the-user approach as with app-v sequences. That being so a Win10 VDI then would have merit.
So recently got going on standing one up (XenDesktop 7.13 back-end). Tested adding a few of the team to a few random app-v sequences / MSI’s applications and noticed horrible download performance for all our apps/packages in Software Center. For example a 200mb MSI took 40 minutes to download.
Issue was put down to the BITs client configuration. For all workstations in general in an environment there is a cap on download speed. Enclosed illustrates what’s in my lab environment
as you can see there is cap’s on performance at certain times of the day. That makes sense for the general workstation population in an environment particularly for remote users over VPN as SCCM does not have an elegant way to identify a user that roams between local and VPN.
As such of course for VDI its not a requirement so in order to switch off I inserted a GPP into my GPO to set no limit on download rate. Registry key is called EnableBitsMaxBandwidth and set to 0 (located under HKLM \Software \ Policies \ Microsoft \ Windows \ BITS)
once I place was rocking and rolling and downloads flew along
