Better performance? An assembly file or crusged down part file?

Just getting going on a design, where I will need to work around my customer supplied data, The data is a rather large and contains 79 surface part files, I currently have 2 options:

A) carry the 79 part files in a part file ass'y & design around that - top level file size:40,922 kb

(smaller file size, but has 79 interior part files)

or

B) Crush my assemby file down to a part file & design around that- crushed part file size: 221,862 kb

Please advise whhat would run faster?
