RPi4 performance compared to Odroid-N2 #43863
A non-scientific test:

Odroid-N2 using AstroPi3 setup
Raspberry Pi4 using Stellarmate
RemoteDesktop into these using NoMachine: No debugging enabled, Storage to the internal (Rpi4 or Odroid-N2) storage,

1) Capture dummy 1 sec exposure Nikon Z7 (90 MB fits), 1 sec exposure QHY5Ill-M (1.2MB fits) as 2 jobs in the Capture queue,
2) Let the fits previewer display each image as it is captured.

So with the RPi4 KStars Build: 2019-09-08T20:04_46Z (oops, not the latest) about 21 sec.
and the Odroid-N2 Kstars Build: 2019-09-24T09:50:13Z about 14 sec.

The difference could be attributed to:
Kstars version (I wouldn't think so)
the number of CPU cores/speed
the speed of the storage device (Rpi4 -> SD, Odroid-N2 -> eMMC)

Memory did not appear to be an issue.
If anyone else has both devices, it would be nice to see if this is reproducable.

Cheers

50% faster on the Odroid N2. Impressive. It might be due to the EMMC. What memory card are you using? Could you try this test again with SD overclocking on the RPi4 in the boot config?
dtparam=sd_overclock=84
Thank you.

I haven't tried overclocking the RPi4, but I just tried writing to a SD card on the Odroid-N2 -> about 19 sec.
