PgConf.Russia 2016

The talk describes performance benchmarking results of PostgreSQL on modern Hi-End servers. 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 performed for different postgres versions (9.4, 9.5, 9.6) to check new features designed to increase performance on multiprocessing architectures.

Diasoft Platform company's technology solutions for migration of applications from proprietary DBMS (on the examples of Oracle and Microsoft SQL Server) to PostgreSQL will be presented in the talk. These solutions are implemented in Diasoft Database Adapter software.

Our technology solutions allow to automate: 1) migration of database schema (including translation of stored procedure and function code); 2) migration of data; 3) migration of client applications without any change in their source code.

More than 300.000 developers use technology platform "1C:Enterprise" as a main development tool. I'll tell you about architecture and features that made "1C:Enterprise" one of the most popular development environment in Russia and CIS and about growing popularity of PostgreSQL amongst 1C users.
