title: Entity Framework 4 and Poco and Linq2Sql performance
body: <p>I`m thinking of using POCO instead of automatically generating the entities, cause i don't want any dependency on the framework</p>
  
  <p>i was wondering if that will have any performance hit, I`m not sure if having to dynamically proxy my entities at run-time will affect performance ,</p>
  
  <p>also i wonder if it gonna be faster if i just let EF4 generate the model for me.</p>
  
  <p>I care about performance a lot in my current project and I have read many times about how L2S is slightly faster than EF2 but I'm not sure about EF4, so now I wonder if I will have performance issues by using EF4 instead of Linq2SQL.</p>
  
  <p>I really wanna use POCO; that is why I prefer EF4 but then again I don't wanna have performance issues.</p>
  
  <p>EF4 and Ling2SQL are the only options for me because I can't use native ADO.net or any other ORM, so can you please share your experience about EF4 and Linq2SQL from a performance perspective?</p>
  
  <p>thanks in advance.</p>
