The block theme (tested as Twenty Twenty-Four ) has seen What performance improvements minor performance changes. The median maximum contentful paint time (LCP) has been reduced by 7 milliseconds (~5%), while the median time to first byte (TTFB) has been reduced by 10 milliseconds (~14%). While new features usually come with some overhead, these data suggest there is still room for improvement in the future.
The classic theme (tested as Twenty Twenty-One) showed a small performance regression. The median maximum contentful paint time (LCP) increased by 1 millisecond (~1%), and the median time to first byte (TTFB) increased by 1.2 milliseconds (~3%).
Major Improvements
Optimize the transient and timeout options in get_transient function
Remove outdated polyfills dependencies
Deprecated polyfills such as wp-polyfill, wp-polyfill-inert What performance improvements and regenerator-runtime were removed from WordPress’ React script japan whatsapp number data dependencies in #60962. These scripts are no longer required in modern browsers, and sites using React frontends may see modest performance improvements as a result.
Disable automatic loading of large options
In #42441, more fine-grained control over autoloading of options was introduced. WordPress will automatically skip autoloading of large options when an option is added without setting an autoload value. This change is intended to reduce issues with slow database response caused by large autoloaded options.
New “Audit Autoload Options” section in Site Health
#61276 Added a new test to the Site Health section that monitors autoload options. The number and size of autoload options are displayed, and above a What performance improvements predefined threshold (800,000 bytes by default) a “critical” status is displayed, indicating a potential performance issue.
Persistent cache block theme mode
In [58025], the block theme schema caches. Were what is the noindex tag and what is its use? updated to use a short-term cache. In order to extend the performance benefits of these schema caches to sites. That are not running an external object cache . Preliminary benchmarks show that eliminating the block schema cost of loading all Twenty Twenty-Four themes on every request saves about 13% of total server response time.
Introducing the wp-on-async directive as a high-performance directive
In Gutenberg PR 61885, the wp-on-async directive was added. This ensures that when there are multiple directives for the same event. They ja phone number don’t accumulate into one long task. This directive yields to the main thread immediately What performance improvements before calling the action/callback, updates the UI, and then runs the processing code. Core blocks such as navigation, query paging, and search have all been updated to use the new asynchronous callbacks.
