Hi,
I have 2 identical servers with SSAS and identical cubes (second is synchronised with first) - as a load balancing solution. They are not part of a cluster.
With some queries, the run time is significantly different (10 sec vs 1 min). For my test, I clear the cube cache and don't clear the file cache. Query is executed multiple times. Looking at profiler, the main difference is that slow query has multiple 'Query Subcube' '1 - Cache Data' events.
What can be the cause that SSAS chooses different execution plan?
