Performance

What should you look for when testing broadband CPE or Wifi performance?

If you are developing or deploying broadband CPE, routers, or Wifi devices, what are the things you should look for when testing performance? Hint - it's more than just throughput, and having a fully automated system to exercise the entire system is key to ensuring true performance. What is performance testing? What do we mean when we talk about performance testing on a broadband gateway or access point? Read more...

CDRouter Release 10.4 - GRE, Application Latency, TR-069 Bootstrap, and more

CDRouter 10.4 is now available! With some major features and upgrades to performance, TR-069, and more, it’s a great time to upgrade your CDRouter system. Application Latency Performance Testing When it comes to performance testing, layer 2 throughput testing is what most tools stick to. But is it enough? No - “line rate” can only mean so much. CDRouter 10.4 introduces application specific latency test cases for DHCP, DNS, and ICMP, to help you exercise how your devices will actually behave from an end user’s perspective. Read more...

Understanding Performance Results

We get a lot of feedback from our users discovering new and interesting results when combining functional testing with throughput, latency, and loss testing. Having a good understanding of how performance tests work and the caveats around their results can help you determine how your functional tests are impacting performance, and visa-versa. Understanding the theoretical maximum of application data What is “line rate”? CDRouter Performance is designed to measure “application level” throughput. Read more...
