Sorry for the delay
I've tried AWS CLI on IBM i and AIX. Direct Link Connect used to have a 1Gb connection but I've read it was upgraded to 5Gb.
You need to set up the reverse proxy following documentation and you can improve file transfers using parallel jobs and using using some adjustments depending on your OS and S3 client.
On AWS CLI (Python based tool), you can use something like this on your ~/.aws/config file:
[default]
region = us-south
output = json
s3 =
max_concurrent_requests = 20
max_queue_size = 10000
multipart_threshold = 256MB
multipart_chunksize = 128MB
When using IBM i you can also change TCP buffering increasing from 64K (default) to 1MB.
If you need more details you can contact me

Available documentation is here: https://cloud.ibm.com/docs/power-iaas?topic=power-iaas-backup-strategies#cos-over-directlink
