The temperature fields are interleaved with name fields, so I don't think you'd get any extra benefit from SSE. Also, since the temperature field is variable-sized, it would probably not pay off even if it was stored by column.

SSE was successfully applied to finding the delimiter between the name and the temperature, though.

It can still be beneficial - yes you need to load the temperatures individually, but there's enough operations afterward to make it worth it.
