Description

While performance profiling the collection#show page for qr1hi-4zz18-tcnxylwkxg0nfhi, it was observed that the source_summary section itself is taking 20s of time.

We can save all this time delay by adding additional columns in collection data for number of files and content size. These can be computed whenever manifest_text changes and hence can be reused for the life of the collection without wasteful computing.
