The load test encountered significant issues, processing 9000 requests with 5473 timeouts and a 61.6% failure rate. The average response time was 3682.1 ms, with a peak response time of 9919 ms. Both machines reached 100% CPU utilization, leading to severe performance bottlenecks and high failure rates. This indicates the need for substantial optimizations, autoscaling, and further investigation.

Both machines reached 100% CPU utilization, which led to a significant number of request failures (61.6% failure rate).
Implement an autoscaling solution on Fly.io and conduct tests using the same configurations.
