Once again, take the test out to the Net. That’s a big difference from the 40Mb/s in the first test. With both machines wired, it gets even better. Sure, it’s not ideal, but it is neater and considerably faster. Could it be even less chaotic, though? These are the results with a wired server. You’ve already tried the RRUL to simulate a more realistic and challenging condition why not more ideal circumstances? The RTT Fair test will help you see what a round trip under more controlled conditions looks like on your network. They do include ping as well.įor a good RTT test, try running RTT Fair. Instead, they just measure the time it takes for a UDP request to complete the circuit and return to the client. They don’t rely on the target being under a load. The RTT, or Round Trip Transfer tests are actually a lot like the RRUL tests.

This is the sort of thing you’d probably expect from a normal torrent download over the Internet. It’s not as clean as the local network, but it’s still not as messy as the wireless tests. Finally, try testing to the remote server provided by. Clearly, there’s a problem with wireless connections.

Keep in mind that this is the same network as that disaster of a test from before. That’s because there is no opportunity for interference or a lack in signal strength. There’s much less variation in this test. The connection isn’t perfect, but it becomes much more stable with one device being wired. Notice the change when the server is wired. That test was conducted between two wireless devices on a crowded network. The above results are what you don’t want to see, loads of latency and dropped packets. It simulates a torrent download, which is obviously a very strenuous type of network activity and is still very much a real world scenario. If your network is experiencing a bufferbloat, the upload and download numbers will both begin to drop off and ping will increase as the test runs.

The stress of the RRUL test is designed to put a significant enough load on the router to trigger the buffer. That extra buffer is both a weight on the router and it slows down the transfer. It occurs when a router buffers too much data when transferring a large chunk of data or streaming. RRUL was developed by the people at to create network conditions where bufferbloat would come into play to help diagnose and remedy it.īufferbloat is a common problem in networking. The RRUL test tries to simulate a real network work load and capture the way the target machine responds under that load. RRUL stands for Realtime Response Under Load.
