Network was VPC. The EC2 instance had an IG attached, yes, but I'm not sure if you're asking if an internal vs. external URL for S3 was used? Are you saying there's a better endpoint than s3-<region>.amazonaws.com for S3 requests from EC2?

I meant http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-en...

It's a private connection to AWS services including S3. You'd use the same URL as it's a routing basically. No idea if VPC endpoints would be better than IG though. P.S. Just tested and I get about half of the latency on VPC endpoint.

Neat, did not know about that. Will add it to my follow-up benchmarks. Thanks for all the comments. :)
