Response times are slow, iotop reports ~10-15MB/s being written to disk by
The website implements a 'latest' feature, any new photos will requested by
many users at the same time.
I'm thinking nginx is probably getting a request for a photo it doesn't
already have, and while it is retrieving the file from s3, more requests

url until the file has been retrieved)
