Setting Up Bandwidth Measurement

You can enable bandwidth measurement to make all uploads perform a bandwidth measurement prior to transferring regardless of the target rate setting for the server or the transferring user (downloads are not affected).

Stop IBM Aspera Faspex on Demand.
In a Terminal or Command Prompt, execute the command to stop Faspex:
```
asctl faspex:stop
```
Open Faspex.yml with a text editor.
Locate Faspex.yml in the following location:
```
/opt/aspera/faspex/config/faspex.yml
```
Before editing Faspex.yml, create a backup. Open it with a text editor:
Add the bandwidth measurement parameter in Faspex.yml.
Before editing Faspex.yml, create a backup. Open it with a text editor, and add this line at the end of the file:
```
...
MeasureBandwidthOnUpload: yes
```
Start Faspex
In a Terminal or Command Prompt, execute the command to start Faspex with the new setting:
```
asctl faspex:start
```

To verify bandwidth measurement, open IBM Aspera Connect Browser Plug-in and go to Preferences > Bandwidth, click Remove All and make sure Automatically cache measurements obtained during transfer is unchecked. Now log into Faspex and send a package. In the first few seconds of the transfer, Connect Browser Plug-in should show a status of Measuring Bandwidth....
