Symptoms
When a Multidimensional Expressions (MDX) query is executed with a calculated measure in SSAS 2016, 2017 and 2019 tabular instance, the calculated measure runs slow and consumes lots of memories if it uses the / operator.
Cause
An improved DIVIDE function allowing faster performance is available in both MDX and DAX.
Resolution
Use the DIVIDE function instead of the / operator in the calculation.
