None of which is particularly relevant - the likely determinate of backup 
creation time is network speed, of your connection to the internet.

All tarsnap archives are sent over the network, and that's the most likely 
bottleneck.

It's not exactly abnormal, but it is a bit slow - that's around 300 KBps. 
How fast is your ISP connection?

No - Small daily changes will get deduped and only the changes themselves 
will get sent over the wire.  Only the first upload needs to have all the 
data.  Daily changes will be much faster.
