I updated from AOS 5.0.2 to 5.0.3. Now the total savings ratio dropped from 3.36:1 to 2.09:1. I thought it may increase, but it's been a few days and no change. Has anyone else seen this? When I updated to AOS 5.0.2 I saw a huge increase in savings, but now it's back to where it was before.

Update: I submitted a ticket and was told the following: The decrease in the storage capacity optimization value is likely due to a bug (bug # ENG-80651) that was fixed in AOS 5.0.3. This bug was present in earlier 5.0.x releases. This issue is mentioned in the AOS 5.0.3 Release Notes: Incorrect compression ratios are reported if uncompressible data exists in a container where compression is enabled. So, when I thought I had such a great increase in savings, it was a bug, and now that it was fixed in AOS 5.0.3, it's indicating the correct amount (which is what it showed prior to updating to 5.0.1).
