- Internal REST-based throughput simulation
- Automatic mini-scaling (5 → 15 → 30 concurrency)
- Estimated requests per second (req/s)

Throughput Check is a lightweight WordPress performance testing plugin that estimates how many internal REST requests per second your site can process.
Unlike external load testing tools, this plugin runs everything inside your own WordPress environment. It sends controlled concurrent REST API requests to your installation and measures:
-
Average response time
-
Estimated requests per second
-
Server p50 / p95 latency
-
Stability (errors detected or not)
-
A simple performance grade (A–D)
No external services.
No artificial network latency.
No complex setup.
Just a clean internal throughput snapshot.
Why this matters
If you are:
-
Evaluating a hosting environment
-
Comparing staging vs production
-
Preparing for a traffic spike
-
Testing PHP performance after updates
-
Debugging performance regressions
You need to understand how your WordPress installation behaves under internal load.
Throughput Check gives you a quick internal benchmark focused on PHP + WordPress execution capacity — not CDN speed, not browser performance.
How the test works
The plugin:
-
Calls an internal REST endpoint
-
Executes a small but realistic WordPress workload:
-
Multiple
get_option()calls -
A
WP_Query(5 published posts) -
A cache set/get operation
-
-
Runs mini-scaling at:
-
5 concurrent requests
-
15 concurrent requests
-
30 concurrent requests
-
-
Calculates:
-
Client average response time
-
Batch duration
-
Estimated requests per second
-
Server p50 and p95
-
Stability score
-
The result is summarized with a clear performance grade:
-
A: ≥ 120 req/s
-
B: ≥ 80 req/s
-
C: ≥ 50 req/s
-
D: < 50 req/s or errors detected
What this is NOT
This plugin is not:
-
A real-world external load test
-
A CDN benchmark
-
A front-end speed test
-
A browser performance tool
It measures internal PHP and WordPress processing capacity only.
Access
Go to:
Tools → Throughput Check
Click Run Test.
Results are displayed immediately in the admin interface.
No. All requests are internal REST calls to your own WordPress installation.
No. It simulates internal PHP-level throughput only.
External latency, CDN, and network conditions are not included.
Yes. The mini-scaling is lightweight and limited to 5, 15, and 30 concurrent internal requests.
No. The plugin does not send any data to external servers.
The core functionality works without a license key.
