Performance improvement following disk array controller replacement?

An anomalous condition due to conflicting configuration information in disk array DAMC005-3-6 led to an OFFLINE volume and thus a Fatal AMP vproc. Following replacement of the hardware a notable performance improvement was realised, compared to the previous three months. Could this be coincidence or could there have been a gradual degradation to the ultimate failure?
