PHP workers process uncached PHP requests. Too little capacity can create queues during bursts of dynamic activity, but more workers do not fix inefficient code.

Work through the problem in order
- Identify which requests bypass full-page cache.
- Watch concurrency during peaks.
- Treat workers as one part of CPU/RAM/database capacity.
- Optimize expensive plugins and queries before assuming capacity alone is the answer.
Where hosting enters the picture
WPX publishes PHP-worker allocations across current plans, making this a useful comparison dimension for dynamic WordPress and WooCommerce workloads.
