Benchmark

Prerequisites

We tested the speed (using .NET Stopwatch) and memory allocation when parsing a small and a large X12 834 file using the .NET Core 3.1 version of X12 Reader. We did two tests for the large file - with and without splitting. Then we tested the speed and memory allocation when validating the large file.

Added the [Splitter] attribute to the 2000 Loop in 835's template:

[Splitter]
[DataMember]
[Required]
[Pos(7)]
public virtual List<Loop_2000_834> Loop2000 { get; set; }

• Small file

Download the file, that contains a single X12 5010 834 message with 2 employee enrollments. 

• Large file

Download the file, that contains a single X12 5010 834 message with 100 000 employee enrollments.

• System Setup

1. Parsing speed and memory allocation results:

The code we used (set Split = true to enable splitting):

public static void Run()
{
   Stopwatch watch = Stopwatch.StartNew();
   var edi = File.OpenRead(@"C:\Hipaa_834_Large.txt");
   using (var ediReader = new X12Reader(edi, "EdiFabric.Templates.Hipaa", 
      new X12ReaderSettings { Split = false }))
   {
      while (ediReader.Read())
      {
      }
   }
   watch.Stop();
   Console.Write(watch.ElapsedMilliseconds);
   Console.ReadKey();            
}

2. Validation speed and memory allocation results:

The code we used (set Split = true to enable splitting):

public static void Run()
{
   var validation = new List<Task<Tuple<bool, MessageErrorContext>>>();
   Stopwatch watch = Stopwatch.StartNew();
   var edi = File.OpenRead(@"C:\Hipaa_834_Large.txt");
   using (var ediReader = new X12Reader(edi, "EdiFabric.Templates.Hipaa", 
      new X12ReaderSettings { Split = false }))
   {
      while (await ediReader.ReadAsync())
      {
          MessageErrorContext mec;
          var msg = ediReader.Item as TS834;
          if (msg != null)
          {
              validation.Add(msg.IsValidAsync());
          }
      }
   }
   Task.WaitAll(validation.ToArray());
   watch.Stop();
   Console.Write(watch.ElapsedMilliseconds);
   Console.ReadKey();            
}
