forks & Parallelism Tuning

Scale how many hosts run at once.

One at a Time Is Slow

By default Ansible touches only a handful of hosts at once. Across hundreds of servers, that serial pace turns a quick play into a long wait. ⏳

The forks value sets how many hosts Ansible drives in parallel for each task. More forks means more machines working at the same moment.
