We analyze why growing stores hit 40,000 daily program-execution limits even when human traffic is steady — and how edge WAF rules plus KVM NVMe vCPUs remove execution counters. (WPVelocity Modeled Targets: 58 ms Uncapped KVM • 1.3s Modeled LCP • 80 ms Modeled INP).
WPVelocity Engineering Note: Even behind dynamic proxy caches, aggressive scraper bots, XML-RPC brute-force requests, payment webhooks, and pseudo wp-cron hits execute full PHP bootstrap cycles thousands of times per hour, exhausting strict daily execution quotas.
Under our WPVelocity queueing equations, unoptimized defaults push dynamic origin responses toward 429 / Quota Cap under concurrent load.
