1C:ERP: up to 12,000 concurrent users in a single infobase

1C Company has successfully completed this load test of 1C:ERP Enterprise Management. The test was run on PostgreSQL under Linux and took into account the requirements of Russia’s largest companies. The result was an APDEX performance index of 0.856, which corresponds to a “good” rating for a comfortable user experience. This confirmed that solutions built on the 1C:Enterprise platform can be used successfully by the largest companies.

The testing team had the following objectives:

• Address the needs of corporate clients who already use 1C solutions and are moving to Linux and PostgreSQL.
• Use a scenario as close as possible to real-world conditions, with 12,000 users working simultaneously in a single infobase.
• Identify and eliminate potential bottlenecks related to concurrent user activity.
• Ensure uninterrupted operation and system stability.
• Rule out technical (platform-level) errors.

The testing was performed by leading 1C specialists with extensive hands-on experience delivering TsKTP projects (1C’s Corporate Technology Support Center) for corporate clients. The database content and test scenarios were prepared to reflect the requirements of large enterprises.

User activity was simulated with “Test Center”, a tool for automating multi-user load testing of information systems that is part of “1C:Corporate Instrumental Package (KIP)”. The load test bench was a server cluster running on the “1C:Enterprise” platform, version 8.3.27.

Processors: Intel Xeon Gold 6226R(2.9GHz/16-Core/22MB/150W)

Drives: Samsung SAS SSD 2.5'' 1920 GB.

Network: 10 Gbps.

The database was filled with data covering 2 months of operations at a large enterprise, about 10 million documents.
The DBMS, the server cluster, and the load generators with 1C:Enterprise thin clients were deployed on Linux.

The chosen scenario simulated a real load on the system and reproduced the day-to-day work of key ERP users:

• chief production dispatcher;
• local production dispatcher;
• procurement manager;
• sales manager;
• warehouse clerk;
• internal consumption of goods;
• production planning;
• budgeting;
• non-current assets accountant;
• accounts receivable and payable accountant;
• accountant.

All user actions were performed with record-level security (RLS) restrictions in place.

The work resulted in a successful load test of 1C:ERP Enterprise Management with 12,000 users. It showed stable, reliable system performance under a heavy, realistic load, with no technical errors. The test results confirm that 1C:Enterprise can run stably with high performance, and they are being used to further improve 1C:ERP Enterprise Management.
