Django + S3 (boto) + Sorl Thumbnail: Suggestions for optimisation

Question

I am using S3 storage backend across a Django site I am developing, both to reduce load from the EC2 server(s), and to allow multiple webservers (redundancy, load balancing)

Answer 1

sorl thumbnail is now created with remote slow storages in mind. The first creation of the thumbnail is however done quering the storage, for example first accessed from template, but after that the references are cached in a key value store. Still you need the first query and creation, well one solution is to use the low level api sorl.thumbnail.get_thumbnail with the same options when the image is uploaded. When the image uploaded add this thumbnail creation job to a que like celery.
