A slightly different test for compare/contrast.
An 'original' [BCM2835] RPiZeroW with 512MB RAM.
Running RPi-Connect Shell 'locally' from an RPi[5]-4G within my own LAN. RPi[5] is cabled to my home router; the RPiZero W has a wireless association to the AP on the same router.
I have twice run Eric Olson's Pi-Chart benchmark. [ viewtopic.php?t=227177 Concurrently monitoring the Zero with htop via a second RPi-Connect Shell session.
The Pi-Chart code is cpu-intensive: it runs the single cpu at 100% for minutes at a time. But it is not memory-demanding. It rarely swaps, and then only by a few MB.
vcgencmd get_throttled report 0x00
vcgencmd measure_temp reports around 46'C
The RPi-Connect Shell sessions have been completely reliable during these tests.
