Reduce coldstart time more.

[XerTheSquirrel]

The current coldstart time is 4-5 seconds on 512MiB, try to set a target of reducing the coldstart duration by 50%.

OPTIMIZATIONS WILL BE PLACED IN INDIVIDUAL PULL REQUESTS SO THEY CAN BE INDIVIDUALLY REVIEWED AND THAT WAY WE HAVE THEM WITHOUT HAVING ANY DELAYS SO WE CAN TAKE ADVANTAGE OF GOOD OPTIMIZATIONS.

From https://hub.iopipe.com/iopipe-faq/what-is-the-overhead-of-iopipe:

On a Lambda with a memory limit of 512MB (the default) and an API Gateway implementation, the coldstart overhead is about 2.5 seconds and the non-coldstart overhead is about 10ms to 20ms. It should be noted that this time will vary depending on the configuration and the code that is used.

• Library size: 17KB + 11MB of Dependencies
• Average duration added by IOpipe on cold-start invocations: 2.5s
• Average duration added by IOpipe on warm invocations: 10ms to 20ms

The added duration overhead occurs at the end of every invocation when the telemetry is sent to the IOpipe APIs.
