RHEL7 kickstart performance

I've been trying to get my Satellite 5.6 Kickstarts adjusted for RHEL7. In the process, I've noticed that the kickstart process seems to take about twice as long. Granted, my package count has increased from 1200-ish to 1400-ish. On RHEL6.5 a complete install took about 20 minutes. Now it seems that "Starting package installation process" alone takes around 15 minutes and then pack installation itself takes another 20 minutes.

Has anyone else noticed this? Is it to be expected?
