This is because the buffer is going to be re-used for subsequent sorts so we should grab as much memory as we are allowed to. If we hit a constrained memory issue, we could end up allocating less than that.. maybe 1/3 of maxnodes. Since it is only sorting sliNumRecords, it needs to recalculate the # of iterations. | |
