I'd like to improve user profile performance with FSLogix on Azure by optionally moving the C:\Users\local_%username% folder (used for redirections.xml) to the temp D: drive on Azure VMs with a temp disk. e.g. D:\Users\local_%username%
I'm not referring to the C:\Users\%username% but the C:\Users\local_%username% folders.
Currently this isn't configurable but it's referenced at HKEY_LOCAL_MACHINE\SOFTWARE\FSLogix\Profiles\Sessions\[SID]\LocalProfilePath
This would offload IOPs from the OS disk and also make some user profile operations much faster, e.g. Teams cache could be redirected and offloaded to speed up Teams.
The temp disk is generally much more performant than Azure Premium disks.
It also sorts the issue of those local_%username% folders not getting cleaned up after an unexpected reboot/crash. If they're on the temp disk they'll get wiped out after a reprovision instead of having to script the cleanup.
Cloud Cache paths can be customised to use the D: drive but it would be nice to move the redirections to that too.
