The average execution time of the API has decreased significantly during a given period, falling below the mean average minus one standard deviation from the preceding period. While a reduction in execution time could be indicative of optimizations or improvements, it could also suggest that something is wrong, such as incomplete processing, skipped operations, or misconfigured resources. Investigating the root cause is important to ensure that the reduced execution time does not indicate a loss in functionality or compromised service quality.
A drastic reduction in execution time might not always be due to optimization. Attackers could try to exploit certain vulnerabilities in the API by manipulating the requests to bypass time-intensive processes. For instance:
