Hello there, im currently looking at some differences between both ORM's and to get a good feel for both i try to query from one table and simply drop all the data in a DataGridView.
Easy as pie right? Now here is the different SQL's beeing generated NHibernate: "SELECT this_.Debiteur_ID as Debiteur1_0_0_, this_.Debiteurnaam as Debiteur2_0_0_, this_.Entiteit_ID as Entiteit3_0_0_, this_.Sorteernaam as Sorteern4_0_0_, this_.DatumWijziging as DatumWij5_0_0_, this_.Actief_NeeJa as Actief6_0_0_ FROM tbl_Debiteur this_" Enitity Framework: "SELECT [Extent1].[Actief_NeeJa] AS [Actief_NeeJa], [Extent1].[DatumWijziging] AS [DatumWijziging], [Extent1].[Debiteur_ID] AS [Debiteur_ID], [Extent1].[Debiteurnaam] AS [Debiteurnaam], [Extent1].[Entiteit_ID] AS [Entiteit_ID], [Extent1].[Sorteernaam] AS [Sorteernaam] FROM [dbo].[tbl_Debiteur] AS [Extent1]" Okay, so sofar EF wins in readability atleast but i dont intend to actually look at the queries so i'm not worried. I noticed that NHibernate was ALOT slower then EF, the reasons seemed like a mistery to me so i ran SQL Profiler. When i run the NHibernate project the query runs for a duration of 19369 (milliseconds) Then i run Enitity frame work which runs for a duration of 3621 (milliseconds) (I clear caches between the different queries) I then run the query in SQL Management Studio, The NHibernate has a duration of 4291 (milliseconds) I do the same for the Enitity framework which has a duration of 4291 (milliseconds) Can anyone explain to me these durations? mostly the NHibernate time when running it from application code is HUGE. Eventhough the SQL is exactly the same... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "nhusers" group.
