I knew I've seen it somewhere.

"The TCP/IP stack now limits the number of simultaneous incomplete outbound
TCP connection attempts. After the limit has been reached, subsequent
connection attempts are put in a queue and will be resolved at a fixed rate.
Under normal operation, when applications are connecting to available hosts
at valid IP addresses, no connection rate-limiting will occur. When it does
occur, a new event, with ID 4226, appears in the system's event log."
