1. A method comprises:

  • for each of a plurality of dispersed storage networks (DSNs) in a computing system network, identifying sets of dispersed storage (DS) units, wherein a set of the sets of DS unit stores an error coded data file;

    identifying a reference entity within the computing system network;

    for each of the plurality of DSNs;

    determining first data access performance information between the reference entity and a first one of the sets of DS units; and

    determining second data access performance information between the reference entity and a second one of the sets of DS units, wherein determining each of the first and second data access performance information includes;

    determining a likelihood of retrieving a decode threshold number of encoded data slices of at least a portion of the error coded data file;

    determining data retrieval access latency for retrieving the decode threshold number of encoded data slices; and

    generating the data access performance information based on the likelihood of retrieving the decode threshold number of encoded data slices and the data retrieval access latency; and

    storing the first and second data access performance information for each of the plurality of DSNs to produce system data access performance information.
