i have large list in memory, class has 20 properties . i'd filter list based on 1 property , particular task need list of property . query like: data.select(x => x.field).where(x => x == "desired value").tolist() which 1 gives me better performance, using select first, or using where ? data.where(x => x.field == "desired value").select(x => x.field).tolist() please let me know if related data type i'm keeping data in memory, or field's type. please note need these objects other tasks too, can't filter them in first place , before loading them memory. which 1 gives me better performance, using select first, or using where. where first approach more performant, since filters collection first, , executes select filtered values only. mathematically speaking, where -first approach takes n + n' operations, n' number of collection items fall under where condition. so, takes n + 0 = n operation...
