Specify your upload speed
You can specify the default unit of upload speed, or throttle speed, for all new package files you upload.
Unless you want to reduce upload speed to limit the impact on your network, Apple recommends you keep the default setting and allow Transporter to optimize the delivery speed.
Specify your default upload speed
Choose Transporter > Preferences.
Choose one of the following:
Automatic. Choose Automatic if you want Transporter to automatically adjust the upload speed per package file and transfer protocol.
Limit to # MB/s. Limit the upload speed to the number, in megabytes per second (MB/s), you specify.
For more precise delivery control, and to help diagnosis network congestion issues, Apple recommends specifying an initial setting of 12.5, incrementing by 1.25 as needed. For Aspera, you can specify a throttle speed up to 114 MB/s.
For control details, see Upload Speed preferences.
