Uploading small files via WinSCP is very slow

Hi

Compress: Before transfer, compress the smaller files into a single archive (e.g., .zip, .tar.gz). This will:

• Reduce the total number of files being transferred, minimizing overhead.
• Improve the overall transfer speed.

Consider file transfer tools other than WinSCP that might be better optimized for numerous small transfers:

rsync: Highly efficient in synchronizing directories and minimizes unnecessary transfers. Ideal if you repeatedly update your files.

Linux:

rsync -avz source_directory user@ec2_instance_ip:/destination_directory

If you are using Keypair

rsync -avz -e "ssh -i /path/to/your/private_key" source_directory user@EC2_IP_address:/destination_directory

Windows:

Install Cygwin -- Install rsync via Cygwin's setup --Open Cygwin Terminal and use rsync as in the Linux example.

S3 Upload: - This is the Best Part I can say, Information [https://docs.aws.amazon.com/cli/latest/userguide/cli-services-s3-commands.html]( Documentation Link) Use the AWS CLI or SDKs to upload to an S3 bucket and then copy the file into your EC2 instance. This leverages S3's parallelization for large data sets.
