XPO - Updated performance benchmarks (v18.2)

Based on user feedback, we’ve updated our benchmarks against EF 6 and EF Core:

    https://github.com/DevExpress/XpoNetCoreDemos/tree/master/ORMBenchmark

What's New in the benchmark?

• Updated NuGet package version:
  
  • Entity Framework 6.2.0 (EF 6);
    
  • Entity Framework Core 2.1.4 (EF Core);
    
  • eXpress Persistent Objects™ 18.2.3 (XPO).
    
• Graphs and their legends now display ORM versions.
• Each benchmark now also compares ORMs with direct SQL queries to show ORM overhead.
  

Run the updated benchmark tests or review our results here. Example: 

All benchmarks were executed using .NET 4.7.2, AnyCPU release builds (include warm-up), Windows 10 Enterprise x64, local Microsoft SQL Server 2016 Developer Edition, i7-7700 CPU @3.6GHz / 16GB RAM / SSD.

We also contributed to the Dapper.Tests.Performance benchmarks, so you can compare XPO with other micro and macro ORMs. See the results below:

It is an expected result that requests to macro-ORM take more time than requests to micro-ORM or direct SQL queries.

Interesting Support Center tickets

• We fixed an issue with the "The assembly does not have persistent classes" error in the ORM Data Model Designer (T680676);
  
• We described how to create a simple data layer to modify data using XPO and a stored procedure in the same transaction (T690250);
• We showed how to perform a left outer join query using XPO (T691525);
• We updated the K18356: How to use XPO data layer caching in XAF KB article;
• We still receive questions on Mono specifics from Xamarin developers, for instance, about using the System.Data.SqlClient and System.Drawing.Common assemblies in XPO apps (T661502 | T643780).
  

Your feedback counts!

Love XPO and want to help us promote it? Add the package through Nuget.org instead of DevExpress Nuget!
