Chat

Maximum Users 1,500

Notes

The number of concurrent HTTP connections for Chat was configured to the maximum.

CPU and RAM usage were both under 80% when the number of maximum users was reached.

Cloud Station Server

Maximum Number of Concurrently Connected Devices 2,000

Maximum Number of Hosted Files (btrfs) 500,000

Maximum Number of Hosted Files (ext4) 500,000

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.

MailPlus / MailPlus Server

Free Email Accounts 5 (Licenses required for additional accounts)

Maximum number of concurrent users Up to 100

Maximum Server Performance 1,052,000 emails per day, approx. 32GB

Notes

The CPU and RAM usage were both under 80% when testing the maximum number of concurrent users.

Read-write SSD cache was enabled in 5-bay (and above) NAS models with 2 SSDs units installed.

The performance of the mail system will slightly decrease in high-availability mode due to data synchronization between the two servers.

Functions that were enabled in all of the tests above: anti-spam, anti-virus, DNSBL, greylist, content scan, full-text search (English only).
