I'm creating a music rating app and I'm using REST Framework to create API in Django. It's super easy but I'm wondering if there is any big difference in loading time when using big serializers model and small. By big and small I mean like in getting more data. For instance I have a album page where I need to use this serializer.

},

This serializer is rather massive and I only need this data for Albums details page. I also pull this data in Albums list page where I list all my albums and almost all of this data is not used. If I make another serializer, little less complex and use it in albums list page, will there be a drastic difference in load speed?
And if so, can I make a Viewset where the less complex serializer is visible when I access my /albums api url and the more complex serializer is displayed when I access more specific url like /albums/1?
