Issue #12310 has been updated by Patrick Carlisle.

Can you share a manifest that causes this? I don't have enough set up here to 
really show a significant difference.

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
