A computer-implemented method according to one embodiment includes monitoring commands sent from a computer to a remote system and monitoring responses sent by the remote system to the computer in reply to the commands. The computer-implemented method includes determining delays corresponding to amounts of time for the remote system to send the responses to the commands, and storing the commands, information from the responses, and the delays in a database in association with the commands. A computer-implemented method according to another embodiment includes receiving a command from a computer, the command being for execution by a remote system. The computer-implemented method includes searching a database for an entry matching the command. The computer-implemented method includes selecting response data corresponding to the command and a delay value corresponding to the command, and sending the selected response data to the computer after a time delay corresponding to the delay value.
