Hi,
I've just enabled Persona Management across our environment (650 users) and it had a strange result. We were previously using Windows Roaming Profiles and we witness a large amount of reads during the login period, as you'd expect with Roaming Profiles. Having enabled Persona Management, it's flipped the other way, and now I'm seeing less reads, which is expected I guess as that is the point of Persona, but loads of writes. The high amount of writes has brought our environment to a standstill! Users are reporting 30-45 minute logins, they're just sitting on the Windows 7 Welcome screen with the spinning blue circle.
Upon checking Resource Monitor on the Profile Server (Windows Server 2008 R2) it appears to be System Volume, NTFS Master File Table and NTFS Volume Log that are top of the write culprits.
Has anyone come across this before?
I've had to disable the Persona Management Group Policy as a result and within an hour things are back to normal levels.
This login issue is crippling us and even using Roaming Profiles we're seeing 10-15 minute logins, hence my reason for going down the Persona route thinking that it would reduce the IO required at login.
Any suggestions would be welcomed!
Thanks in advance.
