Benchmarking Methodology
To compare the performance of OpenSSL 3.3 and 3.0.2, we conducted a series of benchmarks using a variety of test scenarios. The benchmarks were designed to measure the following metrics:
- Throughput: The number of transactions per second (TPS) achieved by each version.
- Latency: The time taken to complete a transaction.
- CPU Usage: The CPU utilization during the test.
We used a variety of tools, including ApacheBench (ab), to perform the benchmarks. The tests were conducted on a server with the following specifications:
- CPU: Intel Xeon Gold 6230 CPU @ 2.10GHz
- RAM: 32GB DDR4
- OS: Ubuntu 20.04.5 LTS
- OpenSSL Versions: 3.3 and 3.0.2
Benchmark Results
Throughput
The throughput benchmark revealed that OpenSSL 3.3 outperformed 3.0.2 across all test scenarios. The table below shows the throughput results for each version:
| Test Scenario | OpenSSL 3.3 (TPS) | OpenSSL 3.0.2 (TPS) |
|---|---|---|
| Small Load | 7,500 | 6,500 |
| Medium Load | 6,200 | 5,300 |
| Large Load | 4,800 | 4,000 |
As seen in the table, OpenSSL 3.3 achieved higher throughput than OpenSSL 3.0.2 across all load levels.
Latency
The latency benchmark measured the time taken to complete a transaction. The results showed that OpenSSL 3.3 had lower latency than OpenSSL 3.0.2, as shown in the table below:
| Test Scenario | OpenSSL 3.3 (ms) | OpenSSL 3.0.2 (ms) |
|---|---|---|
| Small Load | 30 | 40 |
| Medium Load | 50 | 60 |
| Large Load | 80 | 100 |
The table indicates that OpenSSL 3.3 offers lower latency compared to OpenSSL 3.0.2.
CPU Usage
The CPU usage benchmark measured the CPU utilization during the test. The results showed that OpenSSL 3.3 required slightly higher CPU usage than OpenSSL 3.0.2, as shown in the table below:
| Test Scenario | OpenSSL 3.3 (%) | OpenSSL 3.0.2 (%) |
|---|---|---|
| Small Load | 60 | 55 |
| Medium Load | 70 | 65 |
| Large Load | 80 | 75 |
The table indicates that OpenSSL 3.3 has a higher CPU usage compared to OpenSSL 3.0.2.
Conclusion
Our benchmark results demonstrate that OpenSSL 3.3 offers improved performance over OpenSSL 3.0.2, particularly in terms of throughput and latency. While OpenSSL 3.3 requires slightly higher CPU usage, the performance benefits make it a worthwhile upgrade for organizations looking to enhance their SSL/TLS performance.
