Use Case
https://github.com/aws/aws-sdk-cpp/wiki/Improving-S3-Throughput-with-AWS-SDK-for-CPP-v1.9
s3crtclient achieves better performance than s3client. Is there any comparision about s3crtclient and transfermanager?
I tested download 1000 files sequentially and each file is 20MB, the result shows transfermanager costs half time of s3crtclient. During the test, transfermanager reaches 1Gbps bandwidth while s3crtclient reaches 600Mbps at max.
