WPVelocity Runbook: LearnDash, TutorLMS & BuddyBoss Sizing for Logged-In Cohorts
Active students are 100% authenticated — meaning full-page HTML caching is bypassed on every click. We model exact PHP 8.3 worker RSS, Redis 7 memory, and MariaDB InnoDB pools for cohort launches. (WPVelocity Modeled Targets: 165 ms (Dynamic LMS) • 1.5s Modeled LCP • 92 ms Modeled INP).
WPVelocity Engineering Note: Unlike content blogs where 94% of readers are anonymous, LearnDash, TutorLMS, and BuddyBoss compute per-student progression bars, quiz timers, and unread notification counters dynamically. Shared hosting LVE limits (20–30 entry processes) saturate within minutes of a cohort email announcement.

WPVelocity Persistent Cutover Checklist (LMS-CONCURRENCY)
-
Offload all MP4/HLS course video delivery to dedicated streaming CDNs (Cloudflare Stream, Bunny, Vimeo) — never stream video bytes via PHP workers.
wp plugin list --status=active --format=table --allow-root
-
Dedicate ~40% of total VPS DDR5 RAM to innodb_buffer_pool_size so wp_learndash_user_activity indexes stay resident in memory.
wp cache flush --allow-root && redis-cli -s /var/run/redis/redis.sock info memory
-
Throttle WordPress Heartbeat API polling to 60–120 seconds inside lesson screens to cut background admin-ajax.php load by 75%.
curl -I https://store.yourdomain.tld/ | grep -iE "x-litespeed-cache|cf-cache-status"
-
Configure PHP 8.3 opcache.memory_consumption=256 so 45+ LMS & membership plugins never recompile bytecode from disk.

WPVelocity Engineering FAQ: LMS-CONCURRENCY
- Why does WPVelocity assign 148 MB worker RSS to BuddyBoss + LearnDash stacks?
- BuddyBoss social activity streams, group memberships, and LearnDash course steps load simultaneously inside each PHP worker, pushing active per-process memory between 115 MB and 148 MB.
- Can 100 concurrent quiz submissions run on entry shared hosting according to WPVelocity math?
- No — simultaneous uncached POST quiz writes exceed shared LVE entry-process caps (typically 20–30 processes) and return HTTP 508 Resource Limit Reached errors.
