Howdy. I'm a bit confused at what I'm looking at, specifically that there seems to be a jump in execution time (the T+n number) but not the any long-running queries I'd expect to show up with it.
Are there some things that are involved in Rails' view rendering that miniprofiler counts timing-wise that are not profiled specifically here?
You are looking at a massive gap between 2 queries.
What you should do is run a flamegraph (include flamegraph gem and type ?pp=help ) and see why there is such a huge gap.
It is most likely a web request of sorts or IO between those 2 statements.
