I'm running a NodeJS Google App Engine service that retrieves a large file and sends it to a Virtual Private Server hosted on Digital Ocean or AWS. The file is about 5MB and takes up to a minute to send in some cases and often times out. Sending the same file from a client running on on my machine, a VPS, or my teammates computer takes less then 5 seconds. After further investigation I discovered that any outgoing request from a Google App Engine instance caps at about 100-200kps regardless of destination. I have not been able to find any information indicating this is something enforced by google.
Is App Engine Capping it? How do I improve the speeds?
