I'm posting this in various locations that are talking about slowness with software/marketplace, because I just managed to fix all of my problems with a simple change:
I just made the smallest change to my computer and all of a sudden the
software/marketplace saw an INCREDIBLE improvement. Usually when
downloading from the marketplace, the software was unusable. However,
after changing my storage location (An SD card) from FAT32 to NTFS it
is at least 10 times faster. Incredible. I highly suggest people give
this a try if they are using FAT32 for their storage media
