Thanks Mohamed. Face recognition of AWS Rekognition is quite fast and normally you get the results within sing digit latency. For the whole life cycle from image upload to Slack notification, normally it will complete withing a second or max couple of seconds. However, naturally, if Lamba cold start is in play, it will increase by 15-20 milliseconds.
