Quoting Andres from upthread:
"To improve something like GetSnapshotData() you first have to come up with
a workload that shows it being a meaningful part of a profile. Unless it
is, performance differences are going to just be due to various forms of
noise."
If you think this is a worthwhile improvement, you need to figure out a way to
reliably test it in order to prove it.
