The default tcp and clientssl profiles are not optimized for handling S3 traffic
S3 workload performance could be suboptimal.
When LTM is configured in BIG-IP and S3 traffic is received.
Manually configuring the tcp and clientssl profiles with recommended values can improve S3 traffic performance with BIG-IP acting as a proxy.
The new s3-tcp and s3-default-clientssl profile are optimized to handle S3 traffic and improve GET, PUT, STAT and througput performance for S3 flows.
