Why Is phpMyAdmin Working Too Slow?

[CptCruiser]

I conducted a test. I fetched 3000 topics with long lines using PHP from MySQL using the PDO system to display on the page. It read all of them within 1 second. Perhaps it took even less time, but I didn't calculate it. However, the phpMyAdmin application sometimes takes 20-30 seconds to open. Pages load extremely slowly. With SQL commands being this fast, why is this application extremely slow?
