 If you want to compare your data transfer performance to others, you can use the [TACC NetSage Portal](https://tacc.netsage.io/). For example [this page](https://tacc.netsage.io/grafana/d/-l3_u8nWl/1b22d62) shows transfer rates for Globus jobs between TACC and the rest of the world. In general, you should be able to get at least 1 Gbps transfer speeds.
 
+TACC also has a [Test Data Transfer Node (DTN)](dtn.md), which is useful for getting a performance baseline.

 If you currently use a shell script / cron job to migrate data using scp/sftp/rsync, the Globus CLI is useful for scripting and automation.
