The unix 'time' command is a very unreliable indicator of program performance. Included in those 4 wallclock seconds, for instance, are the time taken to start the perl interpreter; the time taken to read, parse, and compile your script; and the time taken to unload everything at the end, to name but a few.

You might want to look into Benchmark to see how your perl script is really performing. There are also several other great references available with a few moments googling, with more general benchmark advice.
