| Notes |
The number of concurrent HTTP connections for Synology Chat was configured to the maximum.
CPU and RAM usage were both under 80% when the number of maximum users was reached. |
| Recommended Number of Hosted Files |
100,000 |
| Recommended Number of Concurrent Sync Clients |
200 (the number of connections that can be maintained when the recommended number of hosted files was reached) |
| Notes |
The maximum number of concurrently connected devices refers to the maximum number of devices that can remain connected at the same time.
The maximum number of hosted files refers to the maximum number of files that can be indexed and hosted by the Cloud Station Server service. RAM expansion was not used during testing.
Non-encrypted shared folders were used during the aforementioned testing. |

| Notes |
Surveillance Station throughput is tested with Axis network camera, using continuous recording with live view from Surveillance Station and motion detection by camera. Live view and recording are sharing the same stream from the camera.
The maximum channel number also includes devices installed on Virtual DSM.
Total FPS may be affected by other services running at the same time (e.g., archive tasks performed by Archive Vault). |
| Recommended Number of Hosted Files |
100,000 (applies to files indexed or hosted by Synology Drive. For file access through other standard protocols, refer to the File Services section above) |
| Recommended Number of Concurrent Sync Clients |
200 (the number of connections that can be maintained when the recommended number of hosted files was reached) |
| Notes |
Exceeding the limits above may result in longer response time in file operations.
EXT4 file system and non-encrypted shared folders were used during the aforementioned testing. |
| Maximum Users |
200 |
| Notes |
Multiple files were opened for testing and each file was edited by 30 users simultaneously.
CPU and RAM usage were both under 80% when the number of maximum users was reached.
Client performance may affect maximum simultaneous editing users. Client PCs used for testing: Intel Core i3-3220 / 8GB RAM |
