etracker aims for maximum stability and minimal resource usage.
etracker implements:
- The BitTorrent Protocol Specification;
- UDP Tracker Protocol for BitTorrent;
- Tracker Returns Compact Peer Lists;
- IPv6 Tracker Extension.

- Announce, Scrape;
- Variable interval (4-30 minutes, depending on the load average).
- Optional full scrape (
data.hDATA_FULL_SCRAPE_ENABLE: 0 -> 1).

Where these peaks come from on the chart - I don't know. If this were the result of dos scrape requests, then net-out would be clearly visible, but it will not be at all.
