Yup, it will take longer for a CR-1/IR-1 especially since they seem to be approving both petitions at the same time. The I-129F goes directly to the NVC for a short time and then to the consulate. With the approved I-130, it gets retained until you file and pay $200 for them to release it to the NVC and then more processing (see the
NVC flowchart for CR-1/IR-1) before NVC schedules an interview with the consulate.
I don't think anyone knows exactly how long it's taking yet either after they file for the I-130 to be forwarded before it even gets to NVC.
See my timeline. Both petitions were approved the same day and my I-129F is already at the consulate and only spent 1 day at NVC. If I had filed for the I-130 to be forwarded to NVC, it probably still wouldn't have been forwarded as of today.
