Reliable in the sense that it works and produces results that are likely to be fairly close to the reality you want to measure? Absolutely. Reliable in the sense that you can always rely on it being available? Unfortunately not. The latter is more of a licensing issue, though, which unfortunately also means that it is not likely to be fixed... :( -Toke --- End Message --- ___ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
Re: [Bloat] Is still netperf a valid tool?
Hi Sergio, IMHO netperf is a convenient toll to generate load, and for measuring bufferbloat, or latency under load increase, generating saturating loads is an important step. So I see no reason why the fct that netperf is relatively mature and sees only little change nowadays speaks against using it. I note that optionally the actual latency measurement can/will be performed using irtt... I guess the real experts will be able to offer a more nuanced opinion...

[Bloat] Is still netperf a valid tool?
Hi, I've seen that many of the recommended tools to diagnose/troubleshoot bufferbloat use netperf. Netperf in https://github.com/HewlettPackard/netperf has many years of inactivity. In fact, in recent versions of distros don't include it. So, my question is: is still netperf a reliable tool?
