Terribly slow cold start when in VPC

[Kralizek]

Hi,

we are experiencing extremely slow cold starts when our Lambda is placed in a VPC.
The lambda hosts an ASP.NET Core web site via the serverless application template.

I'm not sure if this is only related to the .NET Core 1.0 runtime or a general problem.

The VPC performance hit is across all Lambda runtimes because there is overhead setting up the Elastic Network Interface. I know the Lambda team is aware of this but that issue is beyond the scope of what we support from this repository.

Ok, sorry. I didn't know it was a common problem.
