Description: Excessive string concatenation is causing lots of allocations and CPU consumption.
Current condition: 36% of your CPU was spent in String.Concat called from FlightJournal.Web.Controllers.ReportController.Export. We expected this value to be <1%.
Recommendations: Consider using cheaper alternatives such as String.Join or a StringBuilder instead.
