Why This Metric Changes Everything

Speed is about perception. Throughput is about capacity. If you only optimize for speed, you may still be vulnerable during traffic spikes.

From Speed Optimization to Real Capacity Testing

Most performance guides focus on caching and CDNs. But without understanding how many requests your WordPress installation can process per second, you’re missing the full picture.

Where Traditional Speed Tests Fall Short

PageSpeed tools simulate a single user. They don’t tell you how your server behaves under concurrency or REST-heavy workloads.

What You Gain from Measuring Throughput
  • Clear processing baseline
  • Hosting validation before launches
  • REST API performance insight
  • Early detection of scaling limits
