I wonder if I should recompile a perl without those options to get better performances

Being a fairly timid sort of fellow, I would just leave the perl that came with your OS as is. But I would also be compiling a non-debug version of perl, installing it into /usr/local/lib, and using it instead of /usr/lib/perl. IIRC (and according to my 'perl -V'), the only args I supply to Configure are '-des', and I have been quite happy with the results. Whether that suits you, however, depends upon what you want from your perl.

Cheers,
Rob
