It seems like you're pretty close with that guess.
https://www.ibisworld.com/us/industry/ohio/bars-nightclubs/1... (2025) estimates there are about 3,000 "bars and nightclubs" in Ohio.
And https://vinepair.com/articles/map-states-with-most-bars/ (2022) estimates there are 1800 bars in Ohio, apparently placing it in the Top 10 of states with the most bars.

Colin (and others?) have been working to reduce the boot time of FreeBSD for a while now. At this point shaving off a few milliseconds is probably a nice win for them.

FWIW, the Use Cases section presents data about the impact in mobile and laptop environments:
On Android, our most advanced simulation that generates memory pressure from realistic user behavior shows 18% fewer low-memory kills, which in turn reduces cold starts by 16%.
...
On Chrome OS, our field telemetry reports 96% fewer low-memory tab discards and 59% fewer OOM kills from fully-utilized devices and no UX regressions from underutilized devices.

If it's actually "phone book", then [1] seems promising.
