Closed huntharo closed 7 months ago

huntharo commented 8 months ago

Motivations

Under k6 test, there is a momentary spike of inits that does not correspond to router instances stopping or starting
This spike in inits causes a large spike in billing which can have a real impact and also makes it difficult to get accurate cost comparisons

Acceptance Criteria

[ ] Understand what causes the spike
[ ] Add Metrics to CloudWatch, if necessary, to debug
[ ] Fix the issue
[ ] Retest to confirm the spike is gone

This did not appear to be an issue after the RAM allocation of the Lambda was increased from 1 GB to 1,769 MB, avoiding throttling that was causing whipsawing.
