At EFI University, your instructors teach engine builders and motorsport calibrators how to dial in fuel tables, ignition timing, and volumetric efficiency with mathematical precision. On efi101.com, however, your WordPress, Divi, and WooCommerce stack is currently forcing every visitor's browser to pull down 368 kilobytes of raw HTML, 93 individual JavaScript files, and 29 render-blocking stylesheets just to open the front page.
What Happens When a Tuner Opens EFI101.com on a Phone
EFI University's hands-on classroom training and online curriculum—backed by your team at (866) 316-7744 and info@efi101.com—have trained thousands of high-performance tuners across the country. While your WP Engine server responds in a respectable 343 ms, the frontend payload attached to your homepage requires 122 separate JavaScript and CSS requests before the layout stabilizes.
When a shop technician or race engineer clicks through to check upcoming EFI Fundamentals or Advanced Tuning class dates from a phone in the dyno bay, parsing 93 scripts and a 368 KB Divi document introduces noticeable lag before course schedules and WooCommerce seat registration become interactive.
Dyno Sheet for Your Frontend: Trimming the 93 global scripts and stripping inline Divi bloat out of the 368 KB HTML document will make class calendars and course checkout load multiple times faster on mobile connections.
Frontend Telemetry Recorded on EFI101.com
| Calibration Point | Recorded on EFI101.com | Optimized Spec | Effect on Course Enrollment |
|---|---|---|---|
| JavaScript Execution Queue | 93 script tags |
4–6 deferred bundles |
93 separate JS files tie up mobile processors while browsing class syllabi. |
| Stylesheet Requests | 29 .css files |
1–2 critical stylesheets |
Browser rendering waits until all 29 stylesheet files finish downloading. |
| Homepage Document Size | 368 KB HTML |
Under 35 KB |
Ten times heavier than lean HTML because Divi embeds massive inline style blocks. |
| Platform Architecture | WP Engine + Divi + WooCommerce | Selective per-route asset loading | Checkout, calendar, and LMS plugins enqueue scripts on pages that don't use them. |
| Origin Server TTFB | 343 ms |
Under 100 ms |
WP Engine hosting is healthy; the bottleneck is 100% in the theme/plugin queue. |
Where the 93 Scripts & 368 KB HTML Come From
In WordPress installations that pair the Divi theme with WooCommerce, payment gateways, event calendars, and online course modules, almost every extension loads its scripts site-wide by default. Even when a visitor is simply reading about your Lake Havasu or touring classroom locations on the homepage, their browser is forced to download checkout validation scripts, slider libraries, and 368 KB of nested Divi shortcode markup.
Practical Areas Where We Can Help Your Team
1. Selective Script Dequeuing (Cutting 93 Scripts Down to Essential Bundles)
We can help you configure route-specific asset rules so WooCommerce payment scripts, course player libraries, and calendar widgets only load on the exact pages where students use them—shrinking your homepage from 122 code files and 368 KB of HTML to a crisp, responsive layout without altering your visual design.
2. Faster Mobile Class Calendar & Seat Checkout
Prospective students comparing hands-on class dates versus online self-paced courses should be able to filter locations, inspect curriculum outlines, and reserve their seat in seconds from any smartphone.
3. CourseInstance & EducationalOrganization Structured Data
Publishing detailed Course and CourseInstance Schema.org JSON-LD markup helps search engines surface your upcoming tuning class dates and curriculum directly in search results.
