  • SSAS Tabular performance – NUMA update

    February 12th, 2014 in Analysis Services, Blog

    How does the SSAS 2012 Tabular model performance change when you add more CPU sockets / NUMA nodes? In my last post (SSAS Tabular NUMA and CPU Cores Performance) I presented the results of some testing I’d been doing on the scalability of the SSAS 2012 Tabular model. Specifically with the performance of distinct count measures over large data volumes (50-200m distinct customers). The conclusion was that moving from 1 NUMA node (CPU socket)…

    [UPDATE] After further investigation, I found that the tests in this post were inacurate and the results unreliable. Updated NUMA test results here In my last post (SSAS Tabular Performance – DefaultSegmentRowCount) I presented some analysis of the query performance impact of changing the DefaultSegmentRowCount setting. This post describes the next tests that I ran on the same system, investigating the impact of restricting SSAS to just 1…
