Answer:
Assuming you are using the AWS CLI to upload data to s3, there are two optimizations to increase the speed:
1) Parallel chunked uploading, which uploads your (large) file in chunks in parallel.
2) use Amazon S3 Transfer Acceleration
This will upload your file to a nearby CloudFront instance
You can enable this in your CLI configuration file, named config in the .aws folder. Add the following lines:
s3 =
max_concurrent_requests = 20
max_queue_size = 10000
multipart_threshold = 64MB
multipart_chunksize = 16MB
max_bandwidth = 100MB/s
use_accelerate_endpoint = true
addressing_style = path
