Is long running query always more heavy than short running query
Query can consume more server resources when executing faster.

For example, recreating index with SOTRT_IN_TEMPDB = ON impacts tempdb.


  This option increases the amount of temporary disk space that is used to create an index, the option could reduce the time that is required to create or rebuild an index when tempdb is on a set of disks different from that of the user database.
