Go crypto operations are super slow on AWS lambda while processing an event, but they are super fast during cold start.

The performance is pretty reliably loke the following:

$ aws lambda invoke --function-name $FUNCTION response.json
$ jq -r < response.json
cold start: count: 10
cold start: total dur: 143.704664ms
cold start: avg dur 14.370466ms
