property Deno.ListenOptions.tcpBacklog

Maximum number of pending connections in the listen queue.

This parameter controls how many incoming connections can be queued by the operating system while waiting for the application to accept them. If more connections arrive when the queue is full, they will be refused.

The kernel may adjust this value (e.g., rounding up to the next power of 2 plus 1). Different operating systems have different maximum limits.
