Notes
The CPU and RAM usages were both under 80% when testing recommended client numbers.
For tested models with expandable memory, the maximum amount of RAM was installed.
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).
