I am thinking about putting ChirpStack v4 LNS on an embedded device and would be great if someone is able to give insights of archivable performances of such setup.
My first idea is to use a ARM32 Cortex A7 1GHz single-core, 512 MB RAM, enabling SQLite and JS codecs.
If someone have experience of such processing power, which would be the maximum uplink throughput and the maximum number of end-devices it can handle?
If needed to know, I have 500 end-devices worst count, and a not that clear worst link throughput (maybe 5 min typ per device, maybe shorter if strangely configured, leading to ~500 ms to ~350 ms overall uplink interval). If I can foreseen supported throughput I may foreseen an avg per-device required min interval.
(aside: if my hardware is insanely poor, may a 2x 64 bit A55 1.7 GHz, 512MB+ RAM do the job?)
Thanks for your insights.
