 ## aquatic_http_load_test
 
+* do single peer_id per connection as in ws, can't hurt and might fix
+  opentracker issues
 * multiple workers is broken
 * try creating sockets with different ports (and also local ips if setting
   enabled), then converting them to mio tcp streams
 * really break and remove connection when reading 0 bytes?
 * think about how to fully load opentracker. maybe keepalive can be activated
+* maybe check against other well-known implementations (which hopefully
+  do keep-alive)
 * Don't send keepalive header, it is not necessary with HTTP/1.1? (But
   opentracker might want it)
