Nas Speed Test

NAS hard disks test 2021: The best NAS disks in comparison. Our test deals with the suitable hard disks which you need for your NAS system. You already own a NAS server or you want to buy one, but you don’t have the right hard disks yet? In our article you will find all the points that you should consider before buying a hard drive. A quick speed test shows that transfer rates going TO the NAS (using a 4 GB iso) is about 19 MB/s. Dramatic improvement! Downloading that same file from my NAS to the desktop is about 25 MB/s. May 30, 2017 This Synology NAS already contains python support, so I could start it easily: [email protected]:/volume1/$ python Then just downloaded and started the java version of wifi speed test app, set the IP address of the NAS and started the test: Wow, it was impressive 316 Mbps (40 MB/s). My laptop is using AC wifi. Then I tested the same on my mobile (LG G4) with my WiFi Speed Test app: It was very similar, 33 MB/s.

Internet connection measurement for developers

Speedtest CLI brings the trusted technology and global server network behind Speedtest to the command line. Built for software developers, system administrators and computer enthusiasts alike, Speedtest CLI is the first official Linux-native Speedtest application backed by Ookla®.

With Speedtest CLI, you can easily:

  • Measure internet connection performance metrics like download, upload, latency and packet loss natively without relying on a web browser
  • Test the internet connection of your Linux desktop, a remote server or even lower-powered devices such as the Raspberry Pi® with the Speedtest Server Network™
  • Set up automated scripts to collect connection performance data, including trends over time
  • Use Speedtest in your programs by wrapping it in the programming language of your choice
  • View test results via CSV, JSONL or JSON

Nas Speed Test

Just a quick note on possibilities available to do some bench-marking of NAS performance. Quite often Blackmagic Disk Speed Test or Intel NAS Performance Toolkit are being used for this. But there are some problems with those: first one is nice and cool but for Mac only, second is good but no longer supported by Intel as it reached its EoL.

So if you look for the other options you may use the following:

ToTu Soft LAN Speed Test – they have commercial and free versions, and promise to deliver Mac OS release soon.

NAS performance tester by Ulrik D. Hansen, absolutely free and with source code available (though it only measures read/write speed values).

I really liked this last option as it is portable and allowed me to do some quick tests against iSCSI target hosted on my Synology DS415+ (gigabit Ethernet connection; 1 drive only, no RAID, both data and header digests enabled). You may see test results below.

Using 400 Mb file:

Synology Nas Speed Test App

The same test run a bit later with both header and data digests disabled:

Using 8000 Mb file:

And here is the same test with digests disabled:

Of course this is quick and dirty measurement, but at least now I have some baseline and tool to measure how changes in my infrastructure or its configuration influence performance. For example I saw interesting reports that NFS share on Synology outperform iSCSI target (at least in terms of IOps), and in other source there were graphs showing negligible performance cost of iSCSI digests (alongside these graphs that material emphasized importance of data integrity you gain with digests), but it will be nice to verify all these claims.

Synology Internet Speed Test

UPDATE (20.03.2015): I did the same tests with disabled digests (see additional screenshots above), so performance cost is not entirely negligible, especially for read and for large chunks of date.
