Potential problems:

  1. Measured document hit ratio (17.81%) differs from the offered DHR (37.09%) by -51.98%.
  2. Measured byte hit ratio (8.41%) differs from the offered BHR (38.72%) by -78.28%.
  3. Reported fill count contribution (51.36%) does not match `cachable miss' estimation (62.22%).
  4. Reported fill volume contribution (62.22%) does not match `cachable miss' estimation (75.03%).
