Out of memory issues

[psitem]

Added a couple more monitors to my largest Uptime Kuma instance and found my Pico W-based Pac Ghost stopped functioning with out-of-memory errors, despite free memory being > 3X the size of the /metrics response. Pointing my ESP32-C3 version to the same Uptime Kuma instance also ran into memory problems, somehow despite having ~1.5X the memory of the RP2040 it has marginally less memory free under CircuitPython.

I've opened an issue against the adafruit_requests library highlighting that the memory consumption of accessing request.text is quite bad.

I've been coming to the conclusion that using boards without PSRAM and extra flash is a bad trade-off. There are ESP32-S2FN4R2 boards on Amazon that get below the Pico W's MSRP in multiple quantities and for a couple bucks more there are lots of ESP32-S3 options. Seeing 8M bytes free on my $9 Arduino Nano clone is niiiiice.
