I pointed my workbench to qr1hi api server and accessed /collections/qr1hi-4zz18-zn1m6s2le7dqjfs. I noticed in the workbench log several issues.

• the collection qr1hi-4zz18-zn1m6s2le7dqjfs is retrieved again and again while displaying this collection, (it seems like for each image file display?). Also, numerous /groups calls are made (for each image display it appears). Same with the user object.

• There were several 404 errors accessing the images (For ex: Started GET "/collections/qr1hi-4zz18-zn1m6s2le7dqjfs/000008/index_files/Alignment%20Score%20Distribution%20(Unmated%20Only).png"). Are these avoidable?

What needs to be done: We need to preload these objects and get them only once per page view. Also, need to determine if we can avoid those image fetching requests.

Started GET "/collections/qr1hi-4zz18-zn1m6s2le7dqjfs/000008/index_files/Alignment%20Score%20Distribution%20(Unmated%20Only).png" for 127.0.0.1 at 2015-05-05 12:30:47 -0400
