Dear nvidia team:
When testing the network performance of two Orin devices, we directly connected them through a switch and used iperf for network stress testing. When both Orin devices are running in screen-off mode, the network bandwidth reaches around 8 Gbps. However, when one of the Orin devices enters the desktop environment, the overall network bandwidth drops noticeably to around 6 Gbps. The entire test was conducted using the iperf tool.
Which JetPack SW you’re using to run the test? The latest version is Jetpack 6.1. We would suggest use latest release.
We are using versionJetPack 5.1.2 [L4T 35.4.1] for testing and we want to conduct tests based on Ubuntu20.04.
Which versions we can used?
Hi,
The latest release for Orin NX is Jetpack 6.1. Would suggest upgrade to latest version and try again.
Besides switching to the latest release I will point out something which maybe applies (and maybe it does not apply)…
Before the desktop login only wired networking would normally be present. You can see networking setup with “ifconfig” and “route” (some systems would use “ip -a -s addr” and “ip route”).
Then, if WiFi is enabled, login might switch networking to wireless. Another “ifconfig” and “route” might show up differently at that point, but only if WiFi is enabled. You should make certain that networking is configured the same both when logged out (prior to desktop login) and during desktop login. You could use serial console or ssh login or local non-GUI login for testing before desktop login.
