Consider adding maximum concurrent downloads and uploads setting under Computing Prefs -> network instead of just max bandwidth used per day. 'Maximum simultaneous connections'.
Because with my farm, when a project comes back online the flood of transfers can take down my WIFI and wired connections with a Gigabit Comcast with XB8 modem. Requiring a few reboots to work through the flood. Being able to set to '1' could help maintain stability during such events.

The developers don't hang around on these boards much. The place to request features and have the requests noticed is git-hub where you can also file bug reports etc.

See:
https://boinc.berkeley.edu/wiki/Client_configuration

You may try to adjust the following options in cc_config.xml.

<max_file_xfers>N</max_file_xfers>
    Maximum number of simultaneous file transfers (default 8).
<max_file_xfers_per_project>N</max_file_xfers_per_project>
    Maximum number of simultaneous file transfers per project (default 2).

This is a per client setting.

With the default values a single client should not be able to make a 1 Gbit connection unusable.
Since you mention a "farm" and WIFI beside wired connections you may have lots of clients on many computers.
To get an impression: How many of each?

A bit over 150 WIFI, handful is wired. Used SFF business PCs with cheap USB stick wifi with decent single antenna design. See https://youtu.be/BExPXMEnNLo
I was wondering if it was a setting under the hood, thx I will check it out.
