Description
Profile Management provides various features to improve logon performance. Examples are Profile streaming, Enable profile streaming for folders, Accelerate folder mirroring, Enable the Profile container for the entire user profile, and more. These features are helpful in scenarios where profiles keep growing with daily use.
This document reflects these test cases and their results, compares these features in terms of improving logon performance, and provides two recommended solutions.
Test Environment
Test Machine - Hardware is:
- Operation system: Windows Server 2016
- Memory: 10G
- Processors: 8
Test Profile - contains the following:
- A large file: a VDA installer ISO file, about 2.6G
- A large folder with complex folder structure:
- Location: the 'appdata' folder
- Folder size: about 63 MB
- Total folder number: 1079
- Total file number: 809
- Average file size: about 80 KB
- A larger folder: added to the Folders to mirror policy
Test Cases - each session lasts approximately 6 minutes

Test Case Result Averages
| Test Case # | Profile loading time | Total logon duration | Group policy duration | Shell start duration | Profile unloading time | Total logoff duration | Avg IOPS | Avg IO volume |
|---|---|---|---|---|---|---|---|---|
| Case 1 | 53.81s | 56.48s | 0.89s | 1.51s | 42.49s | 43.67s | 18.8 | 3.74 MB |
| Case 2 | 20.21s | 23.01s | 0.87s | 1.65s | 53.03s | 54.29s | 18.8 | 4.36 MB |
| Case 3 | 0.50s | 3.2s | 0.89s | 1.60s | 11.93s | 13.23s | 20.2 | 5.34 MB |
| Case 4 | 7.27s | 10.00s | 0.84s | 1.60s | 6.72s | 7.95s | 20.6 | 5.46 MB |
| Case 5 | 1.80s | 4.45s | 0.83s | 1.55s | 5.62s | 6.89s | 17.8 | 3.82 MB |
| Case 6 | 2.66s | 5.26s | 0.87s | 1.43s | 3.63s | 4.99s | 15.5 | 5.85 MB |
Performance Analysis
Based on the above test case results, we can conclude:
-
Profile streaming improves both logon and logoff performance significantly. However, if the mirrored folder is large, the performance improvement of logoff is not as significant as that of logon.
-
Accelerate folder mirroring improves logoff performance significantly if the mirrored folder is large.
-
Enable profile streaming for folders always improves both logon and logoff performance especially when folder structure is wide and deep.
-
Enable the Profile container for the entire user profile always improves both logon and logoff performance significantly. However, it does not support multi-session write-back. If we enable the Enable multi-session write-back for profile containers feature, logon and logoff performance will decrease.
Recommended Solutions
In summary, we recommend the following two solutions for improving logon and logoff performance:
Solution 1: Profile streaming + Enable profile streaming for folders + Accelerate folder mirroring all enabled
Performance comparison:
| Parameters | Before | After |
|---|---|---|
| Logon time / Total logon time | 53.81s / 56.48s | 1.80s / 4.45s |
| Logoff time / Total logoff time | 42.49s / 43.67s | 5.62s / 6.89s |
Solution 2: Enable the Profile container for the entire user profile
Performance comparison:
| Parameters | Before | After |
|---|---|---|
| Logon time / Total logon time | 53.81s / 56.48s | 2.66s / 5.26s |
| Logoff time / Total logoff time | 42.49s / 43.6s | 3.63s / 4.99s |
