Question

You are using a 10-Gbps direct peering connection to Google together with the gsutil tool to upload files to Cloud Storage buckets from on-premises servers. The on-premises servers are 100 milliseconds away from the Google peering point. You notice that your uploads are not using the full 10-Gbps bandwidth available to you. You want to optimize the bandwidth utilization of the connection. What should you do on your on-premises servers?

Options

  • ATune TCP parameters on the on-premises servers.
  • BCompress files using utilities like tar to reduce the size of data being sent.
  • CRemove the -m flag from the gsutil command to enable single-threaded transfers.
  • DUse the perfdiag parameter in your gsutil command to enable faster performance: gsutil

Explanation

As the question states that the RTT is 100ms thus low transfer rate is due to the TCP window size that is too small. And the solution is to increase the window size.
