My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory.

For example, data collected on load actions can include navigation start, request start, and speed index metrics. Virtually any application with a user interface can benefit from regular real user monitoring. Providing insight into the service latency to help developers identify poorly performing code.

OPN304 Learnings from migrating a service from JDK 8 to JDK 11 AWS Lambda improved latency by migrating to JDK 11 with Amazon Corretto. OPN402 Firecracker open-source innovation Since Firecracker’s release at re:Invent 2018, several open-source teams have built on it, while AWS has continued investing in Firecracker’s speed.
