IS AWS LAMBDA COLD START STILL AN ISSUE?

Summary from the TLDR Web Dev newsletter

A Lambda cold start refers to the initial delay experienced when an AWS Lambda function is invoked after being idle. The duration of a cold start varies from under 100 ms to over one second, the latter of which occurs in about 1% of all invocations. This article goes into detail on ways you can optimize cold start latency, such as fine-tuning memory for your function, using ARM64 CPU architecture, optimizing function creation methods, and more.
