The report describes performance testing results of PostgreSQL on modern Hi-End IBM servers (POWER8). The main attention was paid to the locks for shared data access and associated bottlenecks. The testing propose was to test the linear read scalability limits with an increase of cores number allocated for PostgreSQL. Testing was done for different DB versions (9.4, 9.5, 9.6) to check new features designed to increase performance on multiprocessing architectures.
