   * notes
     * load testing shows that with sharded state, mio reaches 1.4M responses per second
       with 6 socket and 4 request workers. performance is great overall and faster than
-      without sharding. io_uring impl is slightly behind or slighly ahead of mio, but
-      nothing justifying code complexity and unsafety
+      without sharding. io_uring impl is a lot behind mio impl with new load tester
+  * what poll event capacity is actually needed?
   * clean torrent map in workers, remove it from shared state
   * mio
     * stagger connection cleaning intervals?
