This Magento 2 module adds a router specifically for Magewire requests, shaving off various milliseconds off every request.
By default, when a request to magewire/post/livewire is made, it loops through routers before hitting the standard router which maps the URL path to the right controller. This means that with every request, the securitytxt router, the robots router and the urlrewrite router are used. And the urlrewrite router adds an additional database query. This module adds a new router with ordering 1, preceeding all others.
Simple benchmarking with time and curl was used to determine the request time of Magewire with this module enabled and with this module disabled:
time curl -s -H 'Content-Type: application/json' -d '{}' -XPOST -S http://magento.local/default/magewire/post/livewireIn my case, without the module, request times are between 165ms and 200ms. With the module enabled, request times are between 155ms and 180ms.
