I assume it also benefits from being able to use HTTP persistent 
connections.

The benchmark using virtual threads is very different, it tries to 
establish 10k connections in a burst. Do you know what connection 
backlog is used by Tomcat? It may require adjusting net.core.somaxconn 
(kern.ipc.somaxconn on macOS) and other settings. ~8100 may be 8k and 
maybe there is something in the Tomcat or Spring connection that 
controls this.
