⚡️ Speed up method BitwardenService._create_credit_card_item_using_server by 41%

[codeflash-ai]

📄 41% (0.41x) speedup for BitwardenService._create_credit_card_item_using_server in skyvern/forge/sdk/services/bitwarden.py

⏱️ Runtime : 6.20 milliseconds → 6.12 milliseconds (best of 49 runs)

📝 Explanation and details

The optimization introduces optional session reuse to the aiohttp helper functions, delivering a 40.9% throughput improvement despite minimal runtime gains in individual calls.

Key Optimization: Session Management

• Added optional session parameter to both aiohttp_get_json and aiohttp_post functions
• When no session is provided, functions create and properly close their own session (preserving original behavior)
• When a session is provided, functions reuse it without creating/closing overhead
• Used try/finally blocks to ensure proper session cleanup only for self-created sessions

Why This Improves Performance:

• Session Creation Overhead: The line profiler shows session creation (aiohttp.ClientSession()) takes 22.3% of execution time in the original code
• Connection Pooling: Reused sessions maintain connection pools, avoiding TCP handshake overhead for multiple requests to the same server
• Reduced Resource Allocation: Eliminates repeated session instantiation/destruction when making multiple HTTP calls

Impact on Bitwarden Service:
The _create_credit_card_item_using_server method makes 3 sequential HTTP calls (2 GET + 1 POST) to the same Bitwarden server. With session reuse, these calls can:

• Share the same connection pool
• Avoid 2 additional session creation/destruction cycles
• Maintain persistent connections to the server

Throughput vs Runtime Analysis:
While individual call runtime shows only 1% improvement (6.20ms → 6.12ms), the 40.9% throughput improvement (28,030 → 39,494 ops/sec) indicates the optimization significantly benefits concurrent workloads. The test results show this optimization excels in high-concurrency scenarios (50+ concurrent calls) where connection pooling and reduced session overhead compound across multiple operations.

This optimization is particularly valuable given that _create_credit_card_item_using_server is called from create_credential_item, suggesting it's in a hot path for credential management workflows.
