If you run a number of sudo commands one after the other it only prompts you the first time, that caching functionality to me seems strange as I don't understand it or what it's doing.
It is not the same functionality. su is all-or-nothing. On the other
hand, sudo can be used in a very granular fashion, allowing specific
commands to be run by specific users or groups.
Also, to reduce the number of times you're prompted for a password
while using sudo, you can change the default timeout value. Edit the
/etc/sudoers file and modify the Defaults line and add a
passwd_timeout param. Example:
