OpenSSL 3.3 demonstrates improved memory efficiency across all operations, which is a significant advantage for resource-limited systems.
CPU Utilization
CPU utilization is a measure of how effectively a cryptographic operation uses the available processing power. Lower CPU utilization means less strain on the system, leading to better overall performance.
CPU Utilization Comparison
| Operation | OpenSSL 3.0.2 (%) | OpenSSL 3.3 (%) | Improvement (%) |
|---|---|---|---|
| RSA-2048 Key Gen | 70 | 65 | 6.67 |
| RSA-2048 Encrypt | 85 | 80 | 5.88 |
| RSA-2048 Decrypt | 90 | 85 | 5.56 |
| AES-256 Encrypt | 60 | 55 | 8.33 |
| AES-256 Decrypt | 65 | 60 | 7.69 |
