+Load test applications for aquatic and other trackers, useful for profiling:
 
-### General
+- [aquatic_udp_load_test](./crates/udp_load_test/) - BitTorrent over UDP
+- [aquatic_http_load_test](./crates/http_load_test/) - BitTorrent over HTTP
+- [aquatic_ws_load_test](./crates/ws_load_test/) - WebTorrent
 
-- [aquatic_bencher](./crates/bencher/) - automated tracker benchmarking
-- [aquatic_peer_id](./crates/peer_id/) - extract BitTorrent client information from peer identifiers
