Do you have and anitvirus software installed? It may scan the file at the first usage. To be sure sqlite doesn't read too much I suggest opening Task Manager, choosing column I/O Read Bytes to be shown and run the query. This also can give a hint about the software that possibly reads the file all the this time.
