Keep in mind that if you have any kind of fanout at scale, keeping a few lambda instances “warm” probably won’t improve your throughout much.

Update: found a nice article with metrics re: lambda-backed api gateway but the premise applies to any fan-out.

It's also worth pointing out that if your Lambda is in a VPC its cold start time can be over 10s.
