Lambda latency is increasing when the traffic is high
Hi Team,
I have a lambda which basically performs the data transformation on service response. The lambda duration metrics is slowly spiking when the traffic is increasing.
Referred already :
Things already configured for lambda:
- Auto scaling the provisioned concurrency of lambda.
- I have enabled the X - Ray trace for the lambda.
- Found out that, Invocation phase duration is increasing when there is more incoming traffic.
Screenshots for reference:
Any idea why the invocation phase is increasing & how to handle this ?

I don't think there's enough information here to solve your problem.
For example, if your Lambda function is interacting with a back-end database then it's possible that under load that database is responding slower and that is causing an increase in Lambda function time and latency.
But without a detailed analysis of the code and what it is doing it's complete guess work.
If it were me, I'd be using X-Ray, instrumenting the code and then analysing where the additional latency is coming from when the function is under load.
