I am running ROcksDB on an SSD drive. The results show that the value of 'micros/op' is not equal to 1,000,000 divided by the value of 'ops/sec'. I am trying to understand why this is the case. Could you please explain the exact meanings of 'micros/op' and 'ops/sec'?

Here is a snippet of the results.
