1. A method for improving performance of a task, the method comprising the steps of: a computer detecting a problem with performance of a task in a production environment and in response, the computer determining a recommendation for reducing the problem, wherein reducing the problem further comprises the steps of: the computer reading a log data structure associated with the task; the computer determining from the log data structure that the task is associated with first and second customers; and the computer identifying in the on data structure a number of database transactions performed by the task for the first customer; the problem is that the number of database transactions performed by the task for the first customer exceeds a threshold; and the recommendation comprises: disassociating the first customer from the task; splitting the task into first and second tasks; and associating the second task with the first customer; in response to an approval of the recommendation, the computer modifying performance of the task based on the recommendation for execution in a test environment; the computer comparing performance of the modified task in the test environment to performance of the task without the modification in the production environment; and responsive to a determination that the modified performance of the task in the test environment is better than performance of the task without the modification in the production environment, the computer subsequently performing the modified task in the production environment instead of the task without the modification.
