Solution Performance

NARI* is a leading solution provider of power and automation technologies in China, and its Power Consumption Analysis System* is a fundamental application for the country’s National Grid. Power Consumption Analysis System is used to collect and store data from thousands of geo-distributed sensors, and provides the analysis & dispatching function. The workload is a self defined benchmark to simulate typical customer analysis scenarios.

  • Best performance with NARI Power Consumption Analysis application is achieved when all data tables are loaded into memory for analysis. Limited memory capacity today results in some tables being compressed and then having to be decompressed in serial fashion, which limits achievable performance. Expanding memory capacity to alleviate this bottleneck can often be cost-prohibitive for customers.
  • Not being able to process as many queries per second (QPS) as desired.


Higher memory capacity of Intel® Optane™ DC persistent memory (Memory Mode) helps reduce the in-memory table compression ratio for NARI Power Consumption Analysis. This allows customers to maintain large amounts of data in an uncompressed format, thereby alleviating the added step of decompression before analyzing the data. As a result, it delivers better performance by processing more queries per second (see chart for performance improvement).1 2 3


Better performance at similar cost – NARI customers will benefit from being able to process up to 20% more queries per second, at comparable cost.

Software and workloads used in performance tests may have been optimized for performance only on Intel® microprocessors. Performance tests, such as SYSmark* and MobileMark*, are measured using specific computer systems, components, software, operations, and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products.
