We should always use small file ( i.e. file with less no. of records ) as lookup. The reason is - This file will be kept in main memory ( RAM ) from the starting to ending of the script/graph run. Hence less the file size more performance from server.

Lookup file should be always small. If the data is growing every day then the performance will become poor and its not wise to use bigger file as lookup. It spoils the lookup concept.
