As macdawg posted, you need to consider how the drive is connected to the Mac, ethernet (NAS), USB-C, Thunderbolt, etc etc. There's also the speed of the drive, is it an SSD, a 5400 rpm drive. Are there lots of small files, or large files that matters as well.

for what its worth:
on my system of MacBook Air i7, SSD, on High Sierra, using apple's Time Capsule, over WiFi 2.4ghz, 129GB of APFS indexed data takes between 12 and 15 hours.

The only thing that would make TM faster in 10.14 is if there were separate processes: one process queueing files for upload, the other uploading with maximum bandwidth. This is what Arq does when backing up to the cloud, and in my experience it takes half the time backing up to Backblaze B2 with a 7.5Mbps internet connection than Time Machine takes to backup to a local Time Capsule (and, for that matter, a recently purchased Synology NAS isn't faster either).

It seems as if the Time Machine codebase has not really been updated in the past decade.

I'm using a MBP running 10.13, connected via 802.11ac to the router (which is in the same room).
