After activating S3 for an asset container the entire page and CMS became very slow. Loading a collections page takes about 10 seconds, the homepage about 3 sec. I activated the cache flag in the filesystem config but this didnt result in an improvement. When going offline I can see that its making an API request to S3 for every thumbnail. Is this really necessary since the S3 URL is already in the md file? Is there any way to speed this up? Unfortunately this currently makes Statamic unusable with S3.
