🔴 Common Signs of a Slow Dokan Website

Before optimizing, identify the symptoms:

• Vendor dashboard loads slowly

• Product submission takes too long

• Pages take 5–10+ seconds to load

• Checkout is slow or unresponsive

• Mobile performance is poor

• Google PageSpeed score is low

🧠 Why Dokan Websites Are Often Slow

Dokan adds extra database queries, dashboards, and vendor workflows on top of WooCommerce and WordPress.

Your speed depends on three layers working together:

1️⃣ WordPress core
2️⃣ WooCommerce
3️⃣ Dokan vendor system

If any layer is misconfigured → your marketplace slows down.
