To plan PHP-FPM capacity effectively, first calculate how many workers will fit within the available RAM budget. Separately, estimate how many workers are needed to handle the traffic actually arriving at the pool. pm.max_children<\/strong> It limits the number of workers available simultaneously per pool, but it is neither a visitor count nor a direct throughput value.
