Wagtail is designed for speed, both in the editor interface and on the front-end, but if you want even better performance or you need to handle very high volumes of traffic, here are some tips on eking out the most from your installation.

Editor interface

We have tried to minimise external dependencies for a working installation of Wagtail, in order to make it as simple as possible to get going. However, a number of default settings can be configured for better performance:


We recommend Redis as a fast, persistent cache. Install Redis through your package manager (on Debian or Ubuntu: sudo apt-get install redis-server), add django-redis to your requirements.txt, and enable it as a cache backend:

    'default': {
        'BACKEND': 'django_redis.cache.RedisCache',
        'LOCATION': 'redis://',
        # for django-redis < 3.8.0, use:
        # 'LOCATION': '',
        'OPTIONS': {
            'CLIENT_CLASS': 'django_redis.client.DefaultClient',

Caching image renditions

If you define a cache named ‘renditions’ (typically alongside your ‘default’ cache), Wagtail will cache image rendition lookups, which may improve the performance of pages which include many images.

    'default': {...},
    'renditions': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '',
        'TIMEOUT': 600,
        'OPTIONS': {
            'MAX_ENTRIES': 1000


Wagtail is tested on PostgreSQL, SQLite and MySQL. It may work on some third-party database backends as well, but this is not guaranteed. We recommend PostgreSQL for production use.


The overhead from reading and compiling templates adds up. Django wraps its default loaders with cached template loader: which stores the compiled Template in memory and returns it for subsequent requests. The cached loader is automatically enabled when DEBUG is False. If you are using custom loaders, update your settings to use it:

    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, 'templates')],
    'OPTIONS': {
        'loaders': [
            ('django.template.loaders.cached.Loader', [

Caching proxy

To support high volumes of traffic with excellent response times, we recommend a caching proxy. Both Varnish and Squid have been tested in production. Hosted proxies like Cloudflare should also work well.

Wagtail supports automatic cache invalidation for Varnish/Squid. See Frontend cache invalidator for more information.
