It looks like no one has mentioned the #1 cause of jitter (not latency per se which is an average value), which is WiFi scans. Due to bad engineering, a WiFi chip can either be scanning or transmitting, and background location tasks can request a WiFi scan at any time. Depending on your OS and what else you run, this can cause stutters in the 250ms-1second range.
