----------------------------------------
I've been testing out 2.7.22 as an update to 2.7.19 due to CVE-2013-3567. With
nothing else changed other than the version, performance goes right down the
crapper. I downgraded to 2.7.21 and performance returned to normal.
Here is a test puppet run with 'time' and '--summarize' against a 2.7.22 master
and then a 2.7.19 master.
