Incase any one else has a problem like this figured it out. We have a Eye-Fi memory card in our DSLR that imports wirelessly to iPhoto. My wife shot 93 RAW images this morning of the cats I guess while I was sleeping and never changed the software to import to her iMac and not mine. So they sent to my iPhoto library without me knowing and then began their trip. So it was the background uploader for Photo stream uploading like 3 gigs of useless cat pictures to my iCloud account that was eating up my speed.... I should have known it would have been her fault 😛
