possible performance issue: tiny packets?

[vtjnash]

why does mbedtls send such minuscule packets?

It seems this is configured as the default: https://mbed-tls.readthedocs.io/en/latest/kb/how-to/reduce-polarssl-memory-and-storage-footprint/#reducing-the-ssl-frame-buffer

In their docs, it says the TLS standard mandates a max packet size of 16K.

That is the max for a TLS packets, but it would likely be faster to send many packets at once. Though performance numbers recently elsewhere seem to indicate that the encryption algorithm is slow enough that it doesn't matter about having the extra overhead here
