README
This package provides a workaround to resolve performance and memory bottlenecks in Guzzle requests caused by the New Relic Agent's current implementation of metrics tracking middleware for Guzzle 6 clients.
⚠️ This library is a workaround relying on the current implementation of the New Relic extension!
Test it carefully before to use it with a new extension release.
See Overview section below for more details.
Installation
composer require lcatlett/newrelic-guzzle-client
That's all! The script is automatically imported thanks to Composer autoloader.
Without Composer
ℹ️ You can also copy the file NewRelicGuzzle.php
and include directly in your project. For example, WordPress sites not using Composer can add this file by adding a require(/path/to/newrelic-guzzle-client/NewRelicGuzzle.php)
at the top of wp-config.php
.
Overview
The newrelic extension defines a Php function, a Guzzle middleware to report some metrics on each requests sent from Php.
The current implementation of the New Relic agent extension registers the Guzzle middleware on every new client instance and wraps the request in curl_exec
rather than curl_multi_exec
or a stream. This results in performance issues and memory exhaustion as middleware is re-registered on every request which are then wrapped into a single call.
Issues seen on Pantheon customer sites include increased memory usage and request times, particularly for requests intended to be asyncronous actually being blocking calls. These bottlenecks can often be seen in the Pantheon application container php-slow.log
files where newrelic\Guzzle6
is invoked:

module syncs translations:
