WordPress REST API Performance Analysis

Modern web and mobile apps rely on REST API speed when fetching data from WordPress. A slow API slows down your entire Headless project. Measure your API response times in milliseconds with this tool.

01Why API Speed Matters?

In Headless WordPress architecture, the frontend (Next.js) requests data from the backend (WordPress API) to display content. If the API Response Time is high, **ISR (Incremental Static Regeneration)** build times increase, and dynamic pages load slowly.

02Database & Caching

Factors directly affecting API speed include database query count, server location, and **Object Cache (Redis/Memcached)** usage. A standard WordPress API request can trigger hundreds of unnecessary queries if not optimized.

Latency Measurement

Network delay and processing time between server and client.

Hosting Score

Scoring based on your infrastructure's response to API requests.

Warm-up Test

Difference between uncached (Cold) and cached (Warm) requests.

Frequently Asked Questions

What is an ideal API response time?

Generally, under 200ms is excellent, under 500ms is acceptable, and over 1 second is problematic.

How can I speed up the API?

Using plugins like WP Rest Cache, cleaning the database, and upgrading to a server with a powerful CPU are the most effective methods.

Will this test slow down my site?

No, it puts minimal load on your site as it strictly sends standard 'read-only' requests.
