Performance Benchmarks for WordPress 7.0

[mukeshpanchal27]

As we enter the beta phase for WordPress 7.0, I am opening this issue to gather and track all performance benchmarks. This will help us collaborate more effectively, identify potential regressions, and ensure all performance-related data is centralized in one place.

Feel free to contribute with your benchmarks, results, or any findings related to performance in WordPress 7.0

Previously for 6.7 - #1572

Summary of WordPress Performance Benchmark Results

1. Is the new version faster or slower?

   • The new WordPress version (7.0 Beta 1) is slightly slower than the old version in terms of performance. While most measurements show a small increase in load times, the differences are minimal and shouldn't cause noticeable issues for most users.

2. How significant are the performance differences?

   • The changes in speed are very minor. For example:
     • First Contentful Paint (FCP) (when the first part of the page is visible): 3.8% slower, adding about 7.55 milliseconds.
     • Largest Contentful Paint (LCP) (when the largest visible part of the page is loaded): 3.8% slower, adding about 7.55 milliseconds.
     • Time to First Byte (TTFB) (how fast the server responds): 11% slower, adding about 6.15

Summary of the WordPress Performance Benchmarks

The results compare how the old and new WordPress versions perform. Here's a quick breakdown in simple terms:

---

1. Is the new version faster or slower?

• First Content Display (FCP): No significant change. The new version is barely slower, taking an extra 2.6 milliseconds (a difference of less than 1%).
• Largest Content Display (LCP): A slight improvement (faster). The time dropped by 4.4 milliseconds (1.11% faster).
• Server Start Time (TTFB): A bit slower. It now takes 11.35 milliseconds longer (9.5% slower).
• LCP minus Server Time (LCP-TTFB): Improved (faster). Time reduced by 12.35 milliseconds (4.5% faster).

🤖 AI Summary for Non-Technical Users

Here’s a simple breakdown of the WordPress performance benchmark results for the new version (7.0 Beta 2) versus the old version:

---

1. Is the new version faster or slower?

The new version (7.0 Beta 2) is slightly slower overall compared to the old version. Key performance indicators like how fast the page shows up (FCP and LCP) and how quickly the server sends the first response (TTFB) have all shown small increases in loading time.

For example:

• FCP (First Contentful Paint): The time it takes for part of the page to load increased by about 4% (just 8 milliseconds).
• TTFB (Time To First Byte): The time for the server to respond increased by about 14% (8 milliseconds).

On the server side, key processes like rendering templates and total response time also experienced slight slowdowns. For example

1. Is the new version faster or slower?

• Faster in terms of loading speed: The new version shows improvements in two major performance metrics:
  • First Contentful Paint (FCP): This measures how quickly something first appears on the screen. The new version is about 4% faster, shaving off around 12.7 milliseconds.
  • Largest Contentful Paint (LCP): This measures how quickly the largest visible element (like an image or heading) loads. The new version is nearly 5% faster, reducing the time by around 20 milliseconds.

Summary of the Benchmark Results

Here’s what the performance benchmark tells us about the new WordPress version compared to the old one:

1. Is the new version faster or slower overall?

The new WordPress version is slightly slower than the old version in terms of loading key elements of a page. Most of the load time metrics (like FCP, LCP, and TTFB) are a bit higher (slower) in the new version. While the difference is small, it indicates that the update results in slightly slower performance.

2. How significant are the performance differences?

• On average, the new version is 4-15% slower across key performance metrics:
  • The First Contentful Paint (FCP) and Largest Contentful Paint (LCP) are around 4.85% slower, with an additional delay of around 9-12ms for users to see page content.
