On a non-ancient machine I would have expected the overhead from perl to be less than half a second, more likely even less than 0.1s.

There are many possible reasons I can think of. For example the Perl installation (or one of the modules) could be on a slow NFS mount, or an otherwise very slow file system. Or Perl's module search path contains such a slow file system, so the mere search of a module makes the Perl thing slow.

My first attempt at diagnosing would be to run 

strace perl testdb.pl

Maybe you can already see which system call takes so much time.

If not, install Devel::NYTProf, and follow the instructions for profiling a script, and tell us which routines have the highest exclusive run times.
