context:

we noticed that sending healtchecks in sequence spaced by 100ms dramatically reduced response times
this makes us want to use the same pattern with broadcast messages to see if it reduces lag
before doing so, we would like to reduce the spacing to the lowest possible number that doesn't re-introduce "clogging" to reduce overall transmission latency when/if we use in broadcast
this is the first of several experiments to try to find an optimal spacing

[hotfix] reduce healthcheck spacing to 10ms
