Explanation

Moving data from memory to disk and back again impacts query performance. But if data stays in memory, the response time is much faster. DB2 10.5 introduces BLU Acceleration for next generation in-memory computing. BLU Acceleration provides breakthrough performance by delivering instant insight from operational data and historical data. IBM Power Systems, with the new POWER8 processor, provides industry-leading capability to keep high volumes of data in memory because of its large cache sizes and memory bandwidth. Power Systems are designed to optimize analytics performance for big data.
