EF is horrible. I've every version since V1. Every system I've worked on that used EF needed major code tuning under production work loads. Before compiled queries (4.1? 5?) supporting more than a handfull of users concurrently was hard. Plus it is just a leaky abstraction over SQL. Many hours spent running stuff through EF, looking at the reams of SQL produced, and trying to tweak the EF query to produce the desired SQL. NHibernate or Dapper or even plain ole' stored procs are preferable to me.
