We simulate the performance of the D-Link DIR-868L with the 500 MB service from ONO

The company ONO announced recently their new 500 MB download speed connection in Spain, the first of its kind in the country. Many are wondering if the router they have can support this speed or if they’ll find bottleneck. In this article, we’ll show the performance of the D-Link DIR-868L with this 500 MB connection.

All of the D-Link DIR-868L’s Gigabit Ethernet ports support up to 1000 mbps, so the 500 mbps speed shouldn’t pose a problem. However, the performance of networks that go from the LAN to the WAN make the connection go through the NAT, which means the speeds are slower than a LAN to LAN connection.

To improve the performance, this router features NAT via hardware. To simulate the performance of the router with a 500 MB connection, we’ve done the same as past tests: We used a computer to simulate a remote server (WAN) with Jperf installed, and another one in the LAN with the same program.

If we move 100 TCP threads (something common in a common connection), the router reaches speed of around 903Mbps, almost twice as much as the expected speed. As you can see in the graph, the threads show a constant speed, this performance is normal in routers with NAT software, without this technology, we would see irregular speeds with lots of lag at times.

If we increase the number of TCP threads to 250, the performance starts to decrease, but we can still get up to 725Mbps with this connection.

With 500 TCP threads we still have a margin of 100Mbps in case ONO increases the speed even more, since we could get 596Mbps.

And finally, with 600 threads we got speeds of 578Mbps.

As you can see in these tests, the router performs impeccably in LAN-WAN tests, so you can get the most out of these ultra-fast connections. If you have D-Link DIR-868L or you’re thinking about getting one, you have nothing to fear about its performance with the highest Internet speeds available on the market today.

Can we take full advantage of this connection via Wi-Fi with the 802.11ac standard it features? We’ll discover it soon.
