SDK.finance system performance testing

The SDK.finance system workload capacity is 2700 Transactions Per Second (TPS)

SDK.finance conducted performance testing to define workload capacity and run a Transactions Per Second (TPS) assessment, with the following configuration:

Hardware configuration

• PostgreSQL Server (x1): Intel Xeon Gold 5412U CPU, 256 GB DDR5 RAM, 2x 1.92 TB NVMe SSD Storage (RAID 1)
• MongoDB Server (x1): 8 vCPU, 32 GB RAM, 240 GB NVMe SSD Storage
• App Instances (3-5): 8 vCPU, 16 GB RAM, 240 GB NVMe SSD Storage (Java 17)
• JMeter Farm (1-5): 4 vCPU, 8 GB RAM, 160 GB NVMe SSD Storage (v. 5.6.3)

Please note: The aforementioned performance of 2700 TPS has been achieved using the hardware configuration specified above. Modifications to the configuration may impact system performance.

Test plan

1. Creation of 7 million simulated users with EUR accounts and initial funds.
2. Configuration of transfer limits and commissions.
3. System snapshot generation (PostgreSQL database).
4. Simulated user load testing with 500 concurrent connections (incremental steps of 100 users, 10-second ramp-up, 5-minute duration per step).
   • Random user login and security token acquisition.
   • 100 random account transfers per user.
   • Result screenshots for documentation.
5. Database restoration from snapshot.
6. Application parameter adjustments and restart for subsequent tests.
7. Execution of additional test scenarios (details omitted for brevity).

Outcome

The testing provided valuable insights into system scalability and performance characteristics, ensuring a robust and efficient platform for user demands.
