------------------------------------------------------------------
Attaching screenshots of the network debug tab for a large job. The thrift API
response is around 1.25s, which we could certainly improve on but doesn't
explain the 4~5s delay in rendering the page.
I noticed that the thrift requests are happening serially, which would suggest
the XMLHttpRequest operations are synchronous. This will block the entire
browser and is most likely causing the brunt of the performance issues.

> The web interface is noticeably more sluggish since the revamp. This is most
> noticeable for large jobs, where the job page may display a blank page for
> several seconds before showing anything useful. We need to adapt the API to
> reduce the amount of data fetched to render these pages.
