Issue #12310 has been updated by R.I. Pienaar.
Ran my manifests with various points in the timelines between 2.7.9 and .10:

There's some slow down early on in the series that I will hone into
but it seems I identified the work in #8341 as a posible cause as across the 3
runs with the before and after hash I can reliably see a significant slow down
there, will do some more tests 'morow with the early commits to see whats up
there

Bug #12310: Significant slow down in 2.7.10 apply

I've been exploring approaches for running puppet masterless and in the same
time trying to massage my manifests to be compatible with 2.7.x scoping etc.
I noticed a huge increase in run times between 2.6.9 and 2.7.10 with the same
manifests, using envpuppet and a git clone I've gathered this information:
<pre>
======== 2.6.9
notice: Finished catalog run in 9.95 seconds
envpuppet puppet apply --pluginsync 14.45s user 4.99s system 92% cpu 21.098
total
======== 2.7.9
notice: Finished catalog run in 16.52 seconds
envpuppet puppet apply --pluginsync 21.92s user 6.90s system 93% cpu 30.814
total
======== 2.7.10
notice: Finished catalog run in 21.34 seconds
envpuppet puppet apply --pluginsync 23.58s user 9.42s system 73% cpu 44.662
total
</pre>
2.7.0 to 2.7.9 performs the same. While 2.7.0-9 is already a fair bit slower
than 2.6 was 2.7.10 adds
another 14 seconds to the run using the same manifests on the same machine.
Comparing last_run_summary.yaml files I notice that the big change in run time
info is service:
<pre>
2.6.9: service: 2.920294
2.7.9: service: 8.238562
2.7.10: service: 12.400952
</pre>
But this does not on it's own account for the time increase there seems to be a
hit somewhere like state.yaml handling or report handling or something that
isn't reflected here.
Unsure how to gather more useful information to narrow this down
