Same here. In my case, 1.2s w/ NewRelicTracing enabled vs 270ms w/o NewRelicTracing.

Hi, I succeeded to create an example that causes 446ms -> 33670ms slowness on my laptop. It's nice if you kindly take time to check it 😄 https://github.com/hkdnet/graphql-ruby-nr

After some investigation, I found `NewRelic::Agent::RangeExtensions.merge_or_append` consumes time. You can see a flamegraph with this branch. https://github.com/hkdnet/graphql-ruby-nr/tree/stackprof ^ is a zoomed capture. The pink rectangle is `merge_or_append`. I confirmed 33670ms...
