|
Remarks |
The maximum number of devices connected simultaneously refers to the maximum number of devices that can remain connected at the same time. For more information about file processing capacity, see the reaction time for file processing. The reaction time of the files relates to the preparation time required for other devices to start downloading a 10 KB file from a Synology NAS once the file has been added to the NAS. No RAM extension was used during the test. Unencrypted shared folders were used during the above test. |

Remarks |
The Btrfs file system was used for testing purposes. The maximum number of simultaneous connections refers to the maximum number of connections that can be maintained when the maximum number of synchronized files has been reached. The reaction time of the files relates to the preparation time required for other devices to start downloading a 10 KB file from a Synology NAS once the file has been added to the NAS. For models tested with expandable memory, the maximum amount of RAM has been installed. Unencrypted shared folders were used during the above test. |

|
Remarks |
CPU and RAM utilization were both less than 80% when testing the recommended number of clients. For models tested with expandable memory, the maximum amount of RAM has been installed. SSD read / write cache was enabled on 5-bay (and up) NAS models with 2 SSDs installed. Messaging system performance drops slightly in high-availability mode due to data synchronization between the two servers. Features enabled in all tests above: anti-spam, anti-virus, DNSBL, gray list, content scan, full-text search (English only). |
