APFs on APL vs DOL

Hi

Do we have any explanation why APFs on an APL vs DOL(newly created tables almost same ratios etc in the optdiag) tables with the same table structure in the same environment show rather big differences?

For APL

APFs Issued                  380.9        1114.9      45712      94.0 %

For DOL

APFs Issued                    52.3        133.4        6272      12.0 %

Devices

On the same device

APL

  Reads                                                                        

    APF                          144.4        422.8      17333    100.0 %

    Non-APF                        0.1          0.2          8      0.0 %

    Writes                            0.0          0.0          0      0.0 %

DOL

Reads                                                                  

      APF                            35.6        104.3        4277      20.5 %    

     Non-APF                      137.9        403.7      16552      79.5 %  

     Writes                            0.0          0.0          0      0.0 %

The only difference maybe is that an APL table has a cluster index but the query is select * from table with a full table scan or select min(col1)

where col1 is non index column.
