Case study > Construction > ADFS Performance Testing for Budimex
Edge One Solutions supported Budimex by delivering the project in the SoW / Fixed Price model, performing comprehensive performance testing of the ADFS authentication system to verify its stability and responsiveness under increasing user load.
The project included preparing performance test scenarios, simulating the complete SAML authentication process, testing 8,000 user accounts under loads ranging from 30 to 1,200 concurrent users, and analyzing response times, throughput, error rates, and overall system stability using JMeter and Grafana.
Budimex wanted to ensure that the ADFS system used for user authorization remained stable under high load. The key objective was to verify whether the system could handle up to 1,200 concurrent users logging in without a significant drop in performance.
The challenge was not only to generate load, but also to accurately reproduce the real login process. The authorization system had to be tested in a scenario covering SAML request generation, user login, and SAML response generation.
For a large-scale organization, the stability of such a process is especially important. Login issues may affect employee access to internal systems, project tools, and resources required for daily work.
Edge One Solutions designed and carried out comprehensive performance tests of the ADFS system. The tests were prepared to reflect the real user authorization process and assess system behavior under different load levels.
The scope of work included:
· preparation of performance test scenarios,
· simulation of the user login process,
· reproduction of SAML request and response generation,
· load simulation from 30 to 1,200 concurrent users,
· preparation of tests for 8,000 user accounts,
· execution of tests within a defined duration,
· response time analysis,
· error analysis,
· system throughput verification,
· load distribution analysis,
· preparation of data supporting the assessment of ADFS stability.
The Edge One Solutions team prepared performance tests that reproduced the real user login process. The tests covered three key stages: SAML request generation, user login, and SAML response generation.
The test assumptions included the simulation of 8,000 user accounts, a 100 Mb/s internet connection for download and upload, load levels from 30 to 1,200 concurrent users, and a 10-minute duration for each test.
During the tests, the team analyzed response times, errors, throughput, and load distribution. This approach made it possible to assess how the ADFS system behaved under gradually increasing traffic and whether the authorization process remained stable under high load.
Construction and infrastructure companies increasingly rely on digital systems in their daily operations: project platforms, communication tools, document repositories, financial systems, schedules, and applications supporting investment management.
In this environment, the authorization system is one of the key elements of IT infrastructure. If the login process is slow or unstable, it can affect the availability of many tools used by employees, subcontractors, and project teams.
Performance testing of authorization systems helps reduce the risk of downtime, verify infrastructure resilience under increasing load, and prepare the organization for large-scale operations. For construction companies, this is especially important because infrastructure and construction projects involve many teams, locations, and processes that require reliable access to IT systems.
