Performance analysis of working with databases with Spring and Symfony

The article presents a comparative analysis of the efficiency of work with MySQL and PostgreSQL databases, using the popular Spring (Java) and Symfony programming frameworks. The research was carried out with the use of proprietary test applications that perform CRUD operations on a different number of records. The test results showed that the execution time of writing and deleting data using the Spring application is longer than when performing the same operations in Symfony. On the other hand, in the case of UPDATE and SELECT operations, the operation execution time with the Spring application turned out to be shorter than in the case of Symfony. The test results also confirmed that, regardless of the development framework, MySQL is less efficient than PostgreSQL while operating on 10 000 records except for DELETE, where MySQL combined with Symfony is the fastest
