+### Details
+
+- System: Hetzner CCX41 VPS (16 dedicated vCPUs, Skylake)
+- OS: Debian 10, kernel 4.19.0-8-amd64
+- aquatic commit: 61841fff
+- opentracker also has a single threaded event mode. It didn't perform as well (143k responses/second) as blocking single-threaded mode.
+
+Default settings were used, except that:
+- load test duration = 120 seconds
+- load test multiple_client_ips = true
+- load test worker settings were tuned for best results for each trackers
+- aquatic request_workers was always = 1, only socket_workers setting was raised. Number in table corresponds to sum of both values

 ## Trivia
 
 The tracker is called aquatic because it thrives under a torrent of bits ;-)
