wp-admin taking 4+ seconds to load? Random 504 errors? Wondering which of your 40 plugins is the culprit? SysWP's Admin Health Profiler instruments your live WordPress site remotely — no SSH, no server access needed.
Works on WPEngine, Kinsta, Cloudways, and any managed host. Zero impact on your public-facing site. Activates on demand, deactivates automatically when done.

Every WordPress professional has felt this — but almost nobody has a good way to diagnose it.
The posts list, WooCommerce orders, plugin settings — all loading in 3–8 seconds. Your team loses productivity. It's not a server problem. It's a plugin stacking problem. But which one?
Random timeouts when saving posts, exporting data, or running imports. The hosting support says "it's PHP" but doesn't say which PHP. You're stuck guessing.
Query Monitor shows queries but not the full lifecycle picture. New Relic requires $300/month and server instrumentation. APM tools require root server access most managed hosts don't allow.
Three steps. No file editing. No server access. Deactivates itself automatically.
From the SysWP dashboard, click Start Analysis on any WordPress site. SysWP remotely activates the profiler via the SysWP WordPress plugin — no SSH, no wp-config.php edits, no maintenance mode. The profiler is off by default and adds zero overhead until you trigger it.
The profiler silently instruments every admin page you visit. For each page request it records: time spent in each WP lifecycle phase, all database queries and their durations, all external HTTP calls your plugins make, and memory peak. Each page visit becomes a data snapshot. Visit the pages that feel slow — WooCommerce orders, plugin settings, media library, whatever your pain point is.
Click "Get Report" in SysWP. The profiler deactivates immediately. SysWP renders the full diagnostic report — aggregated phase timings, slowest callbacks (attributed to their plugin), HTTP call map, slowest queries with SQL, and static analysis (autoloaded options, DB table sizes, heartbeat hooks). Then Claude AI reads the report and delivers specific, actionable recommendations.

Each phase uses -PHP_INT_MAX and +PHP_INT_MAX priority hooks to bracket the exact duration from first to last callback.
Seven categories of diagnostic data, aggregated across all your page visits.
Average and P95 milliseconds per lifecycle phase across all captured snapshots. Instantly shows where time is spent: if plugins_loaded takes 1,200ms, you know that phase — not PHP or MySQL — is the bottleneck.
plugins_loaded: 1,240ms avg
admin_init: 380ms avg
admin_enqueue: 95ms avg
Every hook callback taking more than 10ms is captured, attributed to its plugin or theme by file path, and ranked by total cumulative time across all requests. You see the exact function name and which plugin owns it.
plugin: woocommerce
WC_Admin::admin_init() — 284ms
across 5 page requests
Every outbound HTTP request your WordPress makes during admin page loads — captured via WordPress's http_api_debug hook. Grouped by remote host. Identifies chatty plugins calling external APIs on every admin page load.
api.mailchimp.com — 12 calls
www.googleapis.com — 8 calls
→ plugin: mailpoet
Queries taking more than 50ms are captured with their SQL (safe truncation), execution time, and the WordPress call stack that triggered them. SAVEQUERIES is enabled remotely for the profiling session and disabled automatically afterward — no wp-config.php changes needed.
SELECT * FROM wp_posts WHERE...
LIKE '%yarpp%' — 207ms
caller: yarpp_get_related()
Top 30 autoloaded WordPress options by size in KB — with the owning plugin guessed from the option name prefix. Autoloaded options load on every WordPress request. Bloated autoload is one of the most common causes of slow WordPress sites and is invisible without this kind of analysis.
_transient_wpseo (bad!) — 412KB
wpseo_titles — 89KB
Total autoload: 2.1MB
After the report renders, Claude reads the complete profiler data and returns specific, actionable fixes based on your actual numbers — not generic advice. It identifies which plugins to configure differently, which features to disable, and which queries to cache, with the exact settings to change.
"YARPP's related posts query uses LIKE — disable Related Posts on admin pages in YARPP settings → Settings → Disable in admin. Expected: −200ms on all admin pages."
DB Table Sizes
Top 15 database tables by size (MB) from information_schema — spot bloated postmeta, options, or log tables instantly.
Heartbeat Hook Audit
Lists all plugins registered on heartbeat_received, heartbeat_send, and heartbeat_tick — the WP heartbeat runs every 15s and is a common cause of unexpected admin slowdowns.
Active Plugin List
Complete list of active plugins included in the AI analysis context so Claude's recommendations are specific to your installed stack.
Standard profiling tells you a phase is slow. Deep Mode tells you which individual function inside that phase is slow — by wrapping every callback registered on admin_init, init, admin_menu, and admin_enqueue_scripts.
Activate deep mode by appending ?syswp_deep=1 to any wp-admin URL while the profiler is active. Every callback that takes more than 10ms is recorded with its function name, owning plugin, hook, and duration.
Wraps all callbacks at PHP_INT_MAX priority (after all real callbacks run)
Identifies the exact function, not just the hook phase
Opt-in — only active when you append ?syswp_deep=1

Before SysWP, diagnosing slow wp-admin required expensive tools or server-level access.
