Starting with 2.11, the Resilio Connect Agent has an option to set a speed limit.
The Management Console Admin must enable it through the Agent Profile, using the "Enable bandwidth scheduler in Agent UI" setting. It's required to restart the Agent UI after enabling the feature.
To change the bandwidth using the Agent UI go to Options -> User-Controlled. By default, the value is in Kbits per second.
If bandwidth is limited both in the Management Console and in the Agent UI, the lower limit will be applied.
It's also possible to set a weekly schedule with limits on certain days and hours. To set weekly a rule click on a day-hour cell, and put the desired download & upload speed limits. By default, the scheduler has a 2-hours scale, 24-hour format, but the user can manually enter any round hour.
In the scheduler you can extend or shrink a rule by a few hours within one day (spreading a rule to another day is not possible):
- when creating a new rule click and hold a cell and drag it down or up. The rule defined will cover the selected time.
- when adjusting an existing rule, mouse-over the rule's edge and drag it up or down.
The scheduler also supports moving a rule around within a day: click and hold an existing rule and move it up or down. Moving a rule to another day is not possible.
Setting a speed limit value 0 kB/s means that synchronization will be paused. The agent will show a 'paused' tag on the taskbar icon and will report the status of "Paused" to the Management Console. 
Pause implies that the Agent will stop all network activity, but will scan and index new or updated files. Agents prior to 2.10 only pause upload and download data, but continue to sync zero-sized files and file deletions.
