Embodiments in accordance with the present invention disclose a method, computer program product, and system for optimizing performance of a computer backup solution that includes at least two data movers. The automated method includes measuring data mover performance during operation of a backup cycle, and optimizing the performance of data movers by increasing or decreasing the number of threads operating concurrently in the data movers. The method further includes computation of performance rankings of the data movers and shifting workload among the data movers in accordance with their respective performance rankings, such that the computer backup solution converges toward an optimized configuration.
