Potential problems:

  1. Measured document hit ratio (19.46%) differs from the offered DHR (28.79%) by -32.41%.
  2. Measured byte hit ratio (17.49%) differs from the offered BHR (30.16%) by -42.01%.
  3. Reported fill count contribution (52.18%) does not match `cachable miss' estimation (60.68%).
  4. Reported fill volume contribution (57.02%) does not match `cachable miss' estimation (66.16%).
