Methods, systems, and products are disclosed for dynamically provisioning server resources. More particularly, methods, systems, and products are disclosed for dynamically provisioning computer system resources that include monitoring a connection performance parameter of a data communications port operating in a data communications protocol having a connection backlog queue having a connection backlog queue size; and changing the connection backlog queue size in dependence upon the monitored connection performance parameter without interrupting the operation of the data communications port and without user intervention. In typical embodiments of the present invention, monitoring a connection performance parameter includes receiving a connection request and determining that the connection backlog queue is full, and changing the connection backlog queue size in dependence upon the monitored connection performance parameter includes increasing the connection backlog queue size.
