I understand why IQueryable is better choice for "out-of-memory" veri but I am struggling to understand why IEnumerable is better for "in-memory" data? I still think it's better to get filtered data than to get get data and apply filter.

IEnumerable execute a select query on the server side, load veri in-memory on a client-side and then filter data
