Query Sequence - BLAST

Thank you for your answer. Now I've been running some queries from the
genbank directory and each *.ffn file has thousands of short running
queries (each new query starting with a gi followed by a number). As I
am going through the runtime of each of those short queries, I find
that most queries take roughly 30-40 seconds to execute. Why is this
happening? Are these short queries part of a larger query and have
been broken down into smaller pieces that have a short execution time?
