Before i bought my DS1511+ i was looking for some benchmarks and tests for the encrypted performance. I didn’t find any so here they are.
My tested equipment is: Macbook Pro with a SSD drive, connected directly (1gbit link) to the DS1511+ with 3x2TB Seagate ST2000DL003 in Synology Hybrid raid. The tested file was a 3.7gb iso file. I tested with both FTP and AFP with no notable difference.
As you can see from the benchmarks, there is a huge performance hit when using encryption.
I just noticed that the screenshots are in danish, but it should make sense anyway.
Red: Modtaget = Received
Green: Sendt = Sent
Uploading to an encrypted share:
As you can see theres 25% CPU load, with only 11mb/s upload speed.
Downloading from an encrypted share.
Here you can see that the speed is 28mb/s with the same CPU load.
Here are two reference benchmark, from shares that are not encrypted.
