Systems and methods for performing asynchronous input/output (I/O) operations. An example method comprises: initializing a list of sockets that are ready for performing I/O operations; traversing the list of sockets, wherein a traversal operation of the list includes, for each socket referenced by the list: performing I/O operations using the socket, updating a state flag associated with the socket to reflect a state of the socket, updating one or more observed I/O performance statistics of the socket; and responsive to detecting less than a threshold number of I/O operation errors during the traversal operation, updating the list of sockets based on updated endpoint state flags and observed I/O performance statistics.
