This post is more for my own archiving purposes, but interesting enough to share.
Here are some Group Policy settings that will greatly improve login times over an Direct Access connection. Note: test well, there might be some side affects.
- Login times measured with a UMTS – 3G connection: 60-90 seconds 100 – 140 ms latency
- Login times measured with a UMTS – HDSPA connection: 30-40 seconds. 80-100 ms latency
Here is a link with a GPO export that, once configured, will tune devices that are connected via direct access http://ronnyholtmaat.nl/da.html
If result are still not ‘good enough, you might consider the ‘Enable the Always Offline Mode’ http://technet.microsoft.com/en-us/library/hh968298.aspx for example ‘Field Workers’.
