NewRelic Node 22 layer Big increase in PostRuntimeExtensionsDuration

[lzientek]

Description

Since the 11 or 12 december when new project are deployed with an updated newrelic lambda (since arn:aws:lambda:eu-west-1:451483290750:layer:NewRelicNodeJS22XARM64:58) we have an increase in the Lambda duration and mostly in the PostRuntimeExtensionsDuration with an average execution time of 40ms where it was 4ms before (this causes a huge impact on our AWS billing almost 2x on our lambda GB-sec bill without an increase in invocation)

Steps to Reproduce

Use the layers on a ARM64 lambda node 22 since arn:aws:lambda:eu-west-1:451483290750:layer:NewRelicNodeJS22XARM64:58 with tracing enabled, the lambda duration is increased without the layers.

Expected Behaviour

As it was before a PostRuntimeExtensionsDuration of ~4ms.

Hi, we are using lambda with serverless via the node plugin serverless-newrelic-lambda-layers
