Steve,

A Raspberry Pi 3 should work fine for OWAMP if you only want to show loss, 
but probably not appropriate to show jitter.
The Pi 3 has two means of network connectivity.

1) On-board WiFi. Pretty well known to have poor jitter performance, 
especially under load or in a noisy environment. It
only supports 2.4GHz, which is pretty crowded everywhere. Loss is also pretty 
much a given on WiFi.

2) On-board USB Ethernet. USB also has poor jitter performance. This is 
compounded by it being shared (via on-chip hub)
with the external USB ports.
