1C:ERP performance is sufficient for the largest companies
1C Company announces the successful completion of load testing of the flagship 1C:ERP solution for 30,000 simultaneous users in a single infobase based on PostgreSQL DBMS from 1C on Linux.
According to the results of load testing with performance monitoring using the APDEX (Application Performance Index) method, the system demonstrated a performance index of 0.858, which corresponds to the "Good" rating and ensures a comfortable user experience.
The testing has confirmed the high stability and efficiency of 1C:ERP with 30,000 simultaneous users. This corresponds to the size of large companies with hundreds of thousands of employees (not all employees use ERP the whole day). At the moment, 1C Company has not received requests for more than 30,000 users in one ERP database, and the company does not know any enterprises that may have such a request.
Testing conditions
The testing was conducted on the 1C:Enterprise server cluster using the "Test center" tool from 1C:Corporate Toolset. The database size was about 1 TB, and the testing scenario included modeling the operations of key ERP users such as production schedulers, sales representatives, procurement officers, warehouse keepers, accountants, and others.
Results
The test results confirmed that 1C:ERP can run effectively under high load, which makes it an effective solution for automating large enterprises, corporations, and holding companies. The system ensures stable operation even with tens of thousands of simultaneous users, which is especially important for companies with multi-shift schedule and a large number of employees.
