Amazon EC2 / S3 Network Performance

Thorsten von Eicken (CTO at RightScale) did some bandwidth measurements, here an overview of his analysis:

EC2 <-> EC2 (large instances):

• one connection: totally 75 MB/s
• three connections: totally 96 MB/s

S3 <- EC2 (large instance, HTTPS, download):

• one connection: totally 12.6 MB/s
• eight connections: totally 49.8 MB/s

the results for non-SSL (HTTP) are about the same.

S3 -> EC2 (large instance, HTTPS, upload):

• one connection: totally 6.9 MB/s
• twelve connections: totally 53.8 MB/s
