我可以在EntityFramework中的ObjectSet上使用多少I(mǎi)nclude以保持性能？我在我的個(gè)人資料頁(yè)面使用以下LINQ查詢(xún)：var userData = from u in db.Users                         .Include("UserSkills.Skill")                         .Include("UserIdeas.IdeaThings")                         .Include("UserInterests.Interest")                         .Include("UserMessengers.Messenger")                         .Include("UserFriends.User.UserSkills.Skill")                         .Include("UserFriends1.User1.UserSkills.Skill")                         .Include("UserFriends.User.UserIdeas")                         .Include("UserFriends1.User1.UserIdeas")                                where u.UserId == userId                               select u;它有一個(gè)長(zhǎng)對(duì)象圖并使用許多包含。它現(xiàn)在運(yùn)行得很好，但是當(dāng)網(wǎng)站有很多用戶時(shí)，它會(huì)影響性能嗎？我應(yīng)該用其他方式嗎？
