It's VERY strange. It cannot have any affect on the speed.
Are you sure you run the correct version of mysqld ?
That is, I can suspect that either safe_mysqld used wrong .my.cnf or
run wrong mysqld, or when you run mysqld directly you used wrong mysqld
or it used wrong my.cnf. I could start all your tests with
SELECT VERSION(); SHOW VARIABLES; - to be sure you are using correct
mysqld and correct my.cnf.

By the way, if you want to disable query cache you can turn it of with a
command line switch :)
 
Regards,
Sergei
