I use synergy to share a mouse & keyboard between my desktop and laptop.
Whenever I start to download something (for example a Fedora ISO), I lose
my connection for about 30 sec due to the ethernet interface speed change.
Even worse the download fails because the connection is lost for this
brief period of time. I'd suggest that at least this change doesn't occur
when on AC as a default policy, but for me personally a way to disable
dynamic updates per plugin without having to hack the python code would be
nice. I couldn't seem to find anywhere in the documentation that mentions
how to do this.

We have an init-based service now that, upon boot, applies some scheduler
tuning to regexes matching threads.
Below is an example:
# Format is: <groupname>:<sched>:<prio>:affinity:<regex>
kthreads:*:1:*:\[.*\]$
watchdog:f:99:*:\[watchdog.*\]
migration:f:99:*:\[migration\/.*\]
softirq:f:70:*:\[.*(softirq|sirq).*\]
softirq-net-tx:f:75:*:\[(softirq|sirq)-net-tx.*\]
softirq-net-rx:f:75:*:\[(softirq|sirq)-net-rx.*\]
softirq-sched:f:1:*:\[(softirq|sirq)-sched\/.*\]
rpciod:f:65:*:\[rpciod.*\]
lockd:f:65:*:\[lockd.*\]
nfsd:f:65:*:\[nfsd.*\]
hardirq:f:85:*:\[(irq|IRQ)[\-_/].*\]
We would like to move this functionality from the init system to a tuned
profile, but it doesn't seem possible with the current tuned
capabilities/plugins.
In addition to one-shot tuning during profile load, there is also a use-
case for monitoring new processes that are created, and applying this
tuning.
This could be a watchdog/scanning behavior in tuned daemon (not preferred
because it creates background noise), or something more clever using perf
events or even LD_PRELOAD of exec function call.
