Latency of requesting a object from S3 to EC2

Question

What's the latency to GET an object from S3 from an EC2 Instance.

For example, how many ms before the actual data stream for that object starts streaming back when requesting a object by it's full path.

• If the object exists on S3
• If the object does not exist and to send a 404

Latency, not Throughput.

Answer 1

We usually experience latency of around 200-300ms from EC2 to S3. It's much slower than you might expect.
