The reduction in time is not because of backticks, but because you're avoiding the shell metachars, meaning that Perl can go directly to the command, rather than forking the shell first.

If you made the test fair, by perhaps adding a semicolon to the end of your backtick command, you'd see that you're saving nothing, and perhaps even spending more time capturing things that you're just going to ignore.
