Using aws_s3_object upload is 3 times longer to complete than aws cli

Upon some comparison upload times, it was found that terraform aws_s3_object takes three times longer compared to the aws cli command. I am working with 5-6GB file to send to S3. Why does it take so much longer using terraform?

Are there similar tuning options available with “aws_s3_object” similar to boto3 such as TransferConfig that can be optimized to improve this performance?
