backup speed SQL 2000

I'm running a manually written nightly backup script on all dbs on a
server. it's a dev server FYI.
the script does the following for all databases:
dbcc checkdb
dbcc dbreindex (on all relevant tables) -- this is done once a week
only
backup transaction with no_log
backup database
now... the duration for this is around 2 hours, given the number &
size of the databases. however, on the night I do the dbcc dbreindex,
the duration drops to 5 minutes. i've added the dbcc dbreindex to run
on other nights, and yes it drops down to 5 minutes each time. next
time it runs without, back up to 2 hours.....
why?
if any other info is required, i will supply.Specify an output file and check for error messages.
