<div dir="ltr">Hi Toke,<div><br>Do let me know. We're focused on the network i/o testing aspect (per being a WiFi chip vendor) and are intentionally not trying to provide CPU load metrics.

I do! Specifically, I am planning to teach Flent to automatically switch<br>
between iperf and netperf as the underlying test tool[0]. I believe that<br>
there are a few netperf features missing from iperf that Flent currently<br>
uses, so I'll get back to you with actual feature requests for those<br>
once I've had a chance to take a look at this in more detail :)<br>

[0] The main driver for this is netperf's weird license which makes it<br>
impossible to package for FOSS-only distributions; leading to things<br>
