# Scraping Load Testing - Test #4
|
|
|
|
## Summary
|
|
|
|
The load test was conducted with the Fly.io configuration set to a hard limit of 100 and a soft limit of 50. The test involved four phases with varying arrival rates. Despite the adjustments, there were 1329 timeouts (14.8%) but no HTTP 502 responses. The average response time was 3547.9 ms, with a peak response time of 9935 ms. Further adjustments to the artillery timeout configuration are recommended to improve performance.

## Conclusions and Next Steps
|
|
|
|
### Conclusions
|
|
1. **Performance:** The system handled 9000 requests with a mean response time of 3547.9 ms. There were 1329 timeouts but no HTTP 502 responses.
|
|
2. **Response Times:** The peak response time was 9935 ms, indicating that the system struggled under peak load conditions.
|
|
|
|
### Next Steps
|
|
1. **Adjust Timeout Configuration:** Change the artillery timeout configuration to reduce the number of timeouts.
|
|
2. **Further Load Tests:** Conduct additional load tests with the new timeout configuration to assess improvements.
|
|
|
|
By following these steps, we can enhance the system's performance and reliability under varying load conditions.
