Data Source and Methodology
Calculations are based on standard engineering principles. For further details, refer to authoritative data sources such as engineering codes and scientific articles.
All calculations are strictly based on the formulas and data provided by these sources.
The Formula Explained
Latency: \( \text{Latency} = \frac{\text{Total Duration}}{\text{Number of Requests}} \)
Throughput: \( \text{Throughput} = \frac{\text{Number of Requests}}{\text{Total Duration} / 1000} \)
Glossary of Terms
- Number of Requests: Total number of API requests made.
- Total Duration: Total time taken for all requests in milliseconds.
- Latency: Average time taken for a single request.
- Throughput: Number of requests processed per second.
How It Works: An Example
Example: If 500 requests take 1000 ms in total, the latency is 2 ms/request, and throughput is 500 requests/second.
Frequently Asked Questions (FAQ)
What is API latency?
Latency is the time taken to process a single request. Lower latency indicates faster response times.
How is throughput calculated?
Throughput is the number of requests handled in a unit of time, typically requests per second.
