These are due to the filesystem switch, or more specifically the
switch in compression methods used. The result is significantly
reduced disk utilisation (higher compression) but more CPU-intensive
work needed to read and write files. Unfortunate, but true. A slowdown
is expected, as a tradeoff for not shipping a nearly-full disk.
What we've effectively done is reverted to what we had for 10.1.3. So,
a more interesting comparison would be observing build 860 at the side
of build 870. Bear in mind that some activities take a lot longer to
launch the first time after flashing, e.g. Browse and Record, so care
is needed to ensure the comparison is fair.
