Run benchmark on any attached storage device (e.g. eMMC, microSD, NVMe, SATA) and add results under an additional heading.

Also consider running PiBenchmarks.com script.

Network

iperf3 results:

iperf3 -c $SERVER_IP: 924 Mbps
iperf3 -c $SERVER_IP --reverse: 776 Mbps
iperf3 -c $SERVER_IP --bidir: 798 Mbps up, 294 Mbps down

(Be sure to test all interfaces, noting any that are non-functional.)

GPU

glmark2-es2 results:

Heh... it _ran_, but it was painful. Got a score of "0" after many tests reported 0 FPS.

Note: This benchmark requires an active display on the device. Not all devices may be able to run glmark2-es2, so in that case, make a note and move on!

TODO: See this issue for discussion about a full suite of standardized GPU benchmarks.

Memory

One quick note: There is an official Debian image, but also Ubuntu 24.04 Server supports the Mars, but you have to update the bootloader via SPI first, if you want to use that.

At boot, I'm not getting HDMI output, at least not to my typical monitor. Something that seems common with some dev boards.

I was able to SSH in, and it is a device registered to "Guangdong Starfive", with the local hostname milkv. I tried an apt update and got:
