bin/host instances and other Phacility operations commands which operate on a list of instances make a Conduit instances.queryinstances call to admin.phacility.com with limit = 1000 after recent changes connected to T12218. This currently takes about a second to resolve.
It appears to be CPU time because the DarkConsole Services tab looks fine. However, it's currently hard to get a profile off the admin tier:
- Although the XHProf extension is available, the XHProf UI is not installed on admin (and probably should not be).
- You can not easily profile Conduit methods because it's a POST request.
- XHProf does not build on PHP7 (and I'm now on PHP7 locally after T12101). This is a minor issue, but complicates things.
There isn't an easy way to download an XHProf profile (oh, there is, you just have to actually generate the profile first).
- There isn't an easy way to upload an XHProf profile (T7954).
