Bahmni LITE Infra-cost estimates (based on Performance testing)

Comprehensive test results and calculation estimates can be viewed in this google sheet document: Bahmni Lite Setup and Cost Estimation

The below analysis explains the various design factors that were taken into consideration during the performance test calculation process.

Patient Records in DB (prior to running the test): 75000

The given hardware supported 40 concurrent users during our test with acceptable performance. The clinical activities performed under the test were

Based on the above numbers & hardware, we recommend the following:

1. If the expected patient / traffic load matches the test data then, on the same hardware you can run up to 20 clinics (2 users per clinic) or 10 clinics (4 users per clinic).
2. If the expected patient / traffic load is LESS than 75% of the above test, then you can likely run up to 24+ clinics (with 2 users-per-clinic) or 12+ clinics (4 users per clinic).

Patient Records in DB prior to running the tests: 90000

The given hardware supported 70 concurrent users during our test with acceptable performance. The clinical activities performed under the test were

Based on the above numbers & hardware, we recommend the following:

1. If the expected patient / traffic load matches the test data then, on the same hardware you can run up to 35 clinics (2 users per clinic) or 17 clinics (4 users per clinic).
2. If the expected patient / traffic load is LESS than 75% of the above test, then you can likely run up to 40+ clinics (2 users-per-clinic) or 20 clinics (4 users per clinic).

NOTE: The number of users assumed are based on the number of requests sent by a user on an average to the server and typical clinic setup observed from real time sources.
