This extension adds a HTTP middleware to the TYPO3 frontend and backend stack that sets the HTTP header X-TYPO3-PHP-peak-memory with the result of PHP memory_get_peak_usage() in bytes.

This extension is an easy way to get an idea which requests may be memory hungry, and if changes to the codebase affect memory consumption.

The middleware is positioned very early (or late, depending on how you look at it) to catch the majority of the TYPO3 request processing.

The header is added in backend requests, if $GLOBALS['TYPO3_CONF_VARS']['BE']['debug'] is configured to true, and in frontend, if $GLOBALS['TYPO3_CONF_VARS']['FE']['debug'] is configured to true.



You probably want to install this as --dev dependency. The extension currently supports TYPO3 v11 and TYPO3 v12:

$ composer require --dev lolli/peak-memory

TYPO3 Extension Repository

Extension key is registered, but the extension is currently not released to TER.


When debug mode and stuff is on, all HTTP requests that go through TYPO3 add the HTTP header. Use browser inspectors or something to see them.

Tagging and releasing is enabled via the casual github hook.
